It happened twice now, i was carrying a bulbus guy in my inventory, with 3 following me and some lunnar essence to mutate others around my cave base.
when trying to give the potion to the flower when bulbus are too close i think, character tries to give the potion to the bulbus. But he goes in circles and he never catches him, and i cannot cancel the animation. Only solution is to quit the server.
i think i listed the full process above. I was Wolfgang if that helps in any way.
