(I was going to post this then literally got the Discord message before hitting Submit. Leaving it here, with the fix, in case anyone downloaded 9.0.1 this morning & came here from Curse to check Issues).

As of this morning, getting this error on log-in. I get it even after I download the latest version from Curse & Ace3 library.
