My Kerfur kept getting stuck in the lake and the river, inable to get out on its own again, and for me it was impossible to get him witout the diving gear once he was in the lake. Once he got stuck close to the lake hole and therefore he was lost forever. He was just spinning in circles whenever he touched water in the version before this one and he didn't do that ever in the versions before. I really hope that this got fixed. I really love votv, this was just very annoying.

this is an pathfinding bug that's been more or less persistent in the game. dev has tried fixing it but i guess it still happens.
the only real fix is to hotswap between winter mode and the regular version. the AI thinks the river / lake is iced out so it's trying to cross it because its "faster" than moving around it. by swapping between both modes it causes it to refresh the AI nodes so that it pathfinds correctly.
