Removing GUI related Ace options didn't change this behavior.

I locally removed AceComm lib and logic as well, still erroring.

Somehow this was caused by PlayerGUID and PlayerName being global variables. https://github.com/valkyrnstudios/RankSentinel/commit/17d9c61c9e803b239adf73eadca40055fed419bb#diff-8e12ced70ffe478a33e70f3b9109b65d33e2835d1a9895cad7b99734411a36c7L6-L7

Moved to class variables and error went away. https://github.com/valkyrnstudios/RankSentinel/commit/17d9c61c9e803b239adf73eadca40055fed419bb#diff-8e12ced70ffe478a33e70f3b9109b65d33e2835d1a9895cad7b99734411a36c7R30-R31
