Gang garrison 2 crashes after finishing a game in a custom map

[Super Sgt. Brown]

Title says it all. It can happen on any server as long as you finished a game in a custom map. It doesn't always happen at the end of each custom map, but the bug is still frequent.

First: The map is not resized correctly.
Second: If you join a team, your class will be uncontrollable.
Third: If you wait long enough, you'll get a server protocol error and GG2 crashes.
Alternatively, if you try to disconnect the server, it crashes too.

If you try to turn off the computer, GG2 will open an error concerning its window, but it won't close itself. That makes it cancel the "turn PC off" action, meaning you'll have to do a hard reset (whether you hold the ON/OFF button or plug off the Power Cable).

This bug only works on windowed mode, apparently.

This may probably be what people call "The Custom Map Bug", but I'm waiting for someone to approve that.
