Try reinstalling Auctionator, as your install might be corrupted (its supposed to include code that prevents the above errors from happening). Otherwise, try the below:

Could you please run this command in-game directly after loading your character:

/console taintLog 1

And then play until you get the error again? Once you do, please log out (this is crucial, the WoW client uses a buffer for writing to the log and it can take up to 10 minutes for errors to appear) and upload the contents of World of Warcraft\_retail_\Logs\taint.log to https://pastebin.com/ and paste the link here.

This will help me figure out what is causing the error.

Auctionator-9.1.12-bcc.zip

Did you do anything specific to trigger this error?

This would sometimes pop up when I opened the Friends and Guild members tab. To continue I have been /reload, and then it does not pop up for awhile. It's hard for me to reproduce, so you could do the same.

I would have sent this to you a long time ago, but I just now downloaded an old version of !BugGrabber that seems to work with Classic TBC. The version of !BugGrabber that CurseForge delivers does not work in Classic TBC.

This time I just Set Focus on a mob.

Recently merged #1135 which should resolve this. Thanks for the report.
