Hi,
it is partially profile problem, WRobot can't find good position to fish and try to go underwater (you need to blacklist this spot).
But in your case seems to be CTM problem (not that wrobot keep key pressed).
I need more logs / videos to find commonalities. If you have this problem again do not hesitate to activate the radar3d (to see where WRobot wants to go) (and if you have time to do a tools> dev tool> all info)
