When I started DB it took longer than usual to sign in. After some time i got an “unable to connect” error which isnt the bug im reporting here. I was put on offline in steam too. I restarted DB but this time i put my status on online.
Suddenly it kept opening tons of small windows (from steam) every second saying “(friendsname) was unblocked/blocked” and spamming error sounds. I had to close steam + dirty bomb via task manager. I verified the game cache and downloaded two broken game files. Everything is working fine now but it was still very weird.
Short version:
Starting DB puts me in Offline Mode. Switching back to online mode spams error sounds and small windows telling me something about unblocked friends on steam.
