OldGrindBot Townrun loop stuck

[Cr0w]

When running the OldGrindBot the bot get's stuck when bag is full. It teleports to town, does his thing (sell items and stash), tries to go back to instance but here starts the loop. I enter the instance, bot casts his aura and then immediately goes back to town (with scroll or by re-logging to start over until the limit of instances is reached and the bot stops.

Any solutions? Does anyone else has this problem too?
