All of these occurred in multiplayer:
-Occasionally, when traveling to a new area, the screen would randomly get a "drunken" effect. I assume it's the same one as when you drink booze (I don't know as I haven't drank any yet). Happened once to me when ambushed by wild animals on the road, and once to a friend when entering a town. The effect goes away upon leaving and entering a new area.
-Similarly, one specific person is occasionally enters new areas and finds themselves only seeing a black screen and the chat. It seems to occur under the same circumstances; twice when entering a dungeon, and once when loading a save while in a forest. It hasn't happened to anyone else yet.
-If you enter a server with several people, one of them leaves, and you save the game, the save seems to corrupt. It only occurred once (since after it happened we stopped doing it
) so I have no idea if it's a valid thing or not. I wasn't the host so I don't have a save, sadly.
Unfortunately if you need further information I doubt I can provide it, these are merely some observations I noticed while playing.
