Pilots!
After releasing Update 2.1.35 we began receiving reports of the increased occurrence of client crashes during battles. We are investigating this issue and will try to identify and fix the underlying reason as soon as possible.
We do not plan to take the server down during this time, since the issue does not affect all players.
If you are experiencing this issue, please contact Support with detailed information: your operating system, client version (WGC or Steam), at which point in battle the crash occurred, etc. We would also appreciate if you add your client logs to your tickets (found at %appdata%/Wargaming.net\World of Warplanes\).
We appreciate your understanding.
