Hey the webwalker gets stuck on the warning for about 30 seconds and then will run. I suggest disabling it as this is an issue with webwalker, not the script.
Do you have the logger when it got stuck for the mountain trolls? How long did you let it run at vannaka when it got stuck btw? Was it like 5 seconds or a few minutes? Osbot webwalker can take up to like 30 seconds to correct itself (Osbot api, not the script)
