A new issue has arisen with the preferences system.
They seem to not want to display no matter how many times I reinstall BLG. I've tried every combination of add-ons (Support_Preferences, System_BlocklandGlass, and System_ReturnToBlockland) along with solely using RTB; nothing seems to work. I have the slightest feeling i'm missing something within the files as i'm trying not to delete and settings/configurations for my server, player, and other clients. I would be grateful if you could try to (possibly) replicate this issue and fix it.
EDIT:
I started to clean out my add-ons folder to remove useless clients and what-not, but then I found something interesting. Turns out Client_MasterPreferences was the source of this issue.
