It is more random, the leveling up was the only thing common between the two issues though. One was on level up and one was a bit delayed. I'll try to keep a good watch on it to find more info :)
It was popping up the "Must start bot on Molch island" notification and not doing anything. I tend to have keyboard interaction unlocked if me messing with the camera would cause issues
On level up, there is a chance that it will lose recognition of being on molch island and just sit there. I can't seem to fix it without stopping and restarting the bot which is not preferable due to premium. Happened with fishing once and cooking once for me.
