We have also discovered the bug that occurs when you leave splitscreen and start hosting game. There are gonna be additional players in lobby so please, make sure you restart the game. Here are some smaller bugs:
-music can stop in some moments,
-gamepad may act weird if steam is enabled,
-red players sometimes spawning in wrong directions.
If you discover any other bugs contact me or write it in comment. Enjoy!
