Multi-Character Issue (Extension Needed no longer works) (Patreon)

So I had a strange issue with an extension that I needed to make Multi-Character works, it suddenly stopped working and other people are mentioning this as well.

I did not update the webui or do anything, I had left it as is, and out of the blue the extension no longer works. I tried older versions of the webui but it seems to not fix it sadly.

I was going to mention this earlier but I had forgotten about it until I tried to make multi-character works again yesterday!

Sadly the creator of the extension has not updated or made any fixes to it in quite a while so atm I am watching the extension to see if any good forks are made (yes it's on GitHub) that fixes these issues.
