I had a game as Goliath (in the bog map I think) where I ate the first (tiny bug) wildlife I could find (near spawn). I ended up getting stuck eating it, i couldnt stop or use abilities, it just ate and ate for 15 seconds until my evolve bar was almost full, then I could move again. When I ate something else my evolve bar instantly lost the extra points (back to 2 tiny bars).
I’m not sure why it happened. I might have clicked some unnecessary buttons at the time, I think I was trying to eat the other bug beside it and it got a little wonky, but I can’t really remember.
