I have frequently had the same issue but I have not been able to tie it to any specific tank. I have been tracking when, where and how and it seems to be completely random. I have installed the mudpack with NO options selected and the issue persists. This indicates to me that the problem is within the mudpack itself and not anyone feature. I have extensive application testing background and I am rather sure the bug is within the mudpack itself.
I crash occurs independent of tanks, maps, tiers, and standard game options (I ran a pure vanilla game with no modapck features and the crash persistently at random).
After selecting a tank to play, the game finds other players and builds teams. Before the count down to game begins the game is either frozen or completely idle (there is a difference). You can not exit this page as no key has any effect. I have found that terminating the game using the task manager and quickly restarting the game, works. I am entered into the battle AFTER it has started and from that point it plays normally. The issue WILL repeat itself, although again it appears to be at random. After a few times(1,2,3 times), the problem appears to not occur until after the next game launch.
The bottom line is... the game crashes at pre-game team menu, with apparently random reasons. I have a strong suspicion that the crash is being caused by the inter-action of this mudpack with modpacks being used opponents. I can tell this because while trying different servers and playing with tier 2 tanks (where all but me and one player on the other team are bots), the issue still occurs. I would be very agreeable to assisting you play test the mod further to isolate and identify the error.
