I have been suffering some bugs which prevent me from playing:
1. After picking team and loading the map, this kind of message appeared with totally black background: "Variable 'bis_rsrespawncontrolmap_ctrlcontrolsgroup' does not support serialization and should not be stored in the mission namespace" (image_1). But I could still shoot gun, move,.... (without seeing anything), I knew that because I could hear the sounds i made :))

2. There was no respawn button, and for sure I could not join the game, waiting another the round and everything was the same (image_2).

I hope to hear the solutions from DEV team and other players soon,
Thank you!
