Examples of bugs corrected by player reports

We want to thank you for correctly created bug reports! Below you will find some of the bug fixes that were possible with your help. You continue to assist us to make War Thunder better!

• ОТО Melara RЗ armoured cars can now swim.
• Karo Tei type 2 — The 37mm Type 94 cannon has been changed to the 37mm Type 4.

• MBK Pr.186 — Errors in the armour of main calibre turrets where some armoured plates weren't displayed in the armour view in hangar have been fixed.
• T20 — The armour of the upper frontal part has been changed from 76.2 to 63.5 mm according to Royal Army Corps - Technical Situation Report No. 3.
• The incorrect operation of the air horizon on a number of aircraft and the altimeter on the Bf 109 has been fixed.
• The shaking (twitching) of the sight on cannons with stabilizer which manifests itself when using hydropneumatic suspension has been fixed
• Incorrect description of the 12.7mm belts has been corrected on a number of ships.
• For a number of British cannons at the 4-8 inches calibres, shells with remote detonators have been added - according to BR 932 Handbook On Ammunition [1945] и ряду других источников.
• HMS Tiger — Armour belt in the area of ammunition magazines has been fixed.
• Bugs that permitted going beyond the boundaries of the battlefield in the location "Krymsk" have been fixed.
• Bugs that permitted going beyond the boundaries of the battlefield in the location "Port Novorossiysk" have been fixed.

Location and mission updates

• The behavior of AI in the locations "Black Sea Port" and "Kursk" has been improved.
• Several bugs on the following locations have been fixed "Stalingrad", "Mozdok", "Korea", "Krymsk", "Port Novorossiysk", "Finland" and "Coral Islands".

Enduring Confrontation

• New scenario for Enduring Confrontation: naval convoys. On the map border, naval convoys will appear which will move towards the sea ports of their respective team. Whilst the convoy is active, the allied team has additional respawn points close to it. The enemy team will also have respawn points at a distance from the convoy. Based on players feedback and further tests it will be decided whether or not to leave enemy respawn points or change them. The number of ships in the convoy depends on the number of players in the game session and on the port size where the convoy is attempting to reach.
• New scenario for Enduring Confrontation: port attack. Each team will have 3 ports at the start of the mission. Each port has several AI ships which will defend the base. Each port is immediately available for players to capture and there are no additional tasks for capturing the ports. If the convoy from the "naval convoy" scenario reaches its port it is very likely that the AI ships from this port will attack one of the enemy ports and the players will receive additional points for helping them to capture enemy port.
• New scenario for Enduring Confrontation: naval bombers. In case there is an active naval convoy on the map the enemy team may have a bomber which will attack and destroy the convoy. The entire logic of the scenario is working in the same way as for ordinary bombers attacking ground bases, but now their targets are convoy ships.
• [Enduring Confrontation] English Channel is now the mission for combined naval battles (ships and aircraft). In this mission only the allied team will receive additional respawns close to convoy.
• New mission [Enduring Confrontation] Saipan in which is represented only with naval and aircraft which play a secondary role. In this mission, with the appearance of the convoy both teams will receive additional respawns (allied- close to the convoy, enemy - farther away from the convoy).

Ground Vehicle model, damage model, characteristic and weaponry changes

• The damage model for large modules, units and assemblies like the breech, transmission and engines has been reworked. Now, those modules use volumetric technology. So the protecting effect of these modules depends on the trajectory of the shell inside them and the point from which the secondary fragments will be generated by the penetration is now the point of "exit" from the module.
• C1 Ariete - The modification (War kit), that increases the protection level of the hull and turret, has been added.

Smaller updates that came afterwards

12.09.2019 (1.91.0.52)

• A bug where the depth charges on the No.13 Type, 1944, Sumner (DD-692) were displayed incorrectly has been fixed.
• M4A1 (75)W - BR in all game modes has been changed from 5.0 to 3.7.
• P-51K (China) - The vehicle card has been updated. All data has been changed to the correct values. BR has been changed: in AB from 5.0 to 4.0; in RB from 5.0 to 4.7; in SB from 5.3 to 5.0.
• Swift F1, Swift F7 - The type of the aircraft has been changed. Takeoff from an aircraft carrier has been removed.
• The NVD (night vision devices) modification has been added for the Т-80U and Т-80B - The night vision system on these tanks is now available, but only after researching one of the following modifications: “NVD” or “NVD upgrade”.
• NVD has been added for the following vehicles: M41, M42, Т54Е1, Т92, M48A1 (China). NVD are available while in the driver and 3rd person view. Due to the addition of the new modification, the research costs and purchase price in GE and SL of the other modifications have been slightly changed.
• Hawk III - A visual bug where the propeller was always displayed as damaged has been fixed.
• S38, MGB-75, IJN Kuma - The flag animation has been fixed.
• MiG-19PT and F-3D - The indicator for the lead-marker point, for weaponry with radar capability, has been disabled in RB and SB. Radars on these aircraft were only designed to work with the gyro sight in the cockpit, and the data for shooting from the cannon has not been calculated accurately enough, so the radar indication in the HUD for 3rd person view has been displaying incorrectly. Instead of this, we have implemented a correctly working gyro sight in the cockpit which receives data from the radar and displays the lead marker position for cannons based on the information available. The effective operating range is about 500m. When aiming/shooting, the aircraft should not make sharp maneuvers, otherwise the sight will not be able to display the correct lead marker.
• F-4C - The radar sight has been removed. The on-board radar of this aircraft was never designed to work with suspended cannons and was instead designed only to work with guided missile weaponry.
• The HUD display of the radar capture area has been fixed.
• The icons for the NVD and thermal imaging modifications have been visually changed.
• The display of smoke plumes from the jet engines of other aircraft has been fixed.
