it happens quiet frequently.
press ESC doesnt show up any exit button
it can only be exit by closing the game client with windows task manager
then restart the game to normallize
it has been happenning like 3 to 4 months, i think ?
i always keep Aslain's WoT Modpack up to date and has no other mods
i dont know how to upload the specific mods i use from Aslain
P.S. i really like Aslain mods, it really helps the gameplay and has almost everything i need
thank you Aslain
