Bot accidently walking into holes

[Votzap]

Hi, I have been making some own scripts. And I have noticed that sometimes the bot will accidently walk into a hole, and then not be able to come back up. For instance I have been botting in Edron earth elementals and from time to time my bot will accidently move into a hole with bog raiders and die.
Has anyone else encountered this problem?
How can I fix it?
