I see this crash too; also wasn't seeing it before today (though I haven't been botting too much lately). Bot didn't crash if I didn't click Show Mesh and would navigate the mesh if I ran to the spot where it's located, but Show Mesh would 100% reproduce it.

This was the mesh I used to repro the issue:

Authentication in general seemed kind of wonky yesterday, too; if I closed the bot it would take several minutes for my session to actually end.
