I stopped the bot yesterday because of the obvious suspicion of being stuck in a tree for 2 hours. Today I started it again, and within 1 minute it was stuck in a small tree again. I helped it unstuck and less than a minute later it was stuck again.
These two times it was not trying to get to a node though, it was just being stuck. Pretty often it gets stuck at trees for up to a minute aswell.
Here's a youtube video and the log:
