I have been having this same issue. Currently unable to progress into the endgame any further because I can't finish an expedition before the game basically stops working. I have tried just about everything I think of and nothing works. I also know it's not my internet connection, but it does look an awful lot like a DC in game, but the game itself doesn't crash or give a connection failed message or anything. Before yesterday evening, I was able to play the game just fine. If there is a fix for this, please let me know or it looks like I will not be able to play this game any more.

ye seems like we got the same problem friend... can´t fint it anywhere on google that somebody else got that problem...

I have this exact same issue as the both you. LITERALLY can't progress any further due to disconnect and enemy is frozen. CAN't even pass the first floor

I joined a friend with my low level character and I was waiting at the beginning of every level and we did 3 total levels and no dc or what so ever... how is that when I do nothing, nothing happends but when I engage combat It fucks up somehow...

Same issue, mobs stop responding but can still use abilities. 4+ times now all near the end of a run
