Possibly a problem unique to Dried Lake as it has to walk to the area rather than to the portal maybe everyone can confirm they were doing dried lake.
To reproduce it, the timing of full inventory and full map clear has to coincide. So when the bot goes to town to sell the items and comes back, it's going back straight away to town because the map is clear, and therefore has no items to sell to the vendor.
Since the bot doesn't have any items to sell or stash, it doesn't walk to the vendor which means the entrance to dried lake is too far for the bot to detect which causes it to get stuck.
Possible simple fix
make the bot automatically walk to the stash after port (this would also fix the bug that makes the bot go to upper east side of town and get stuck)
