Yep. I get this too along with other aggravating problems.

I am trying to get help from vBulletin on this and several other issues. I cannot migrate to their version 5 because it breaks all of the permanent links!! They changed everything and invalidated permalinks. Very bad idea. All of the links in Gemini that point to threads here... would be gone. Devastating to my situational awareness. So I'm going to need to get this V4 software fixed. It seems to be "new" yet I have not touched the actual forum software in several years. I have a hell of a lot on my plate right now (the last 2 days have been working through upgrade issues on Subversion and Git).

They have advised me to do some maintenance on the databases which I plan for over the weekend in case it scorches something.
