You'll have to restart the client if you get the issue, sorry. I can't replicate the issue on my end, have no other users complaining about it, and can't find any code that would be overriding the client terminating the script. Fortunately it doesn't affect the functionality of the script.
If your inventory is full the bot will eat a food to clear a spot for items to go when you thieve. Is this undesired for the NPC you are thieving from? If so, which NPC?
If your inventory is not full and this is happening please post your settings, etc as I have outlined in my OP so I can narrow down the problem and fix it ASAP.
