Yeah, those are just a few bugs that Kov needs to work on fixing, group glitch, party glitch, bio glitch, y'know. Nothing is perfect! :3 But if your game is crashing I suggest opening up options when you first open the game and turning view distance down, water reflection off, and putting the music and effects sounds lower (I have my music completely off). My game still lags a bit but no crashing if I do what I just mentioned.
