Hi, currently when I adjust the spell list within retail.lua it has no effect on the in-game settings menu/ gameplay experience. It worked as of last version but the newest updates seemingly broke that functionality. I've testing adjusting spell types on multiple spells, and adding new ones. But no matter what I do it never actually affects my in game settings.

Hmm, I can't find any issues changing/adding/removing spells to retail.lua with v9.13. Some things you could try:

• Double check that the retail.lua file you're editing is in the right path (i.e. editing it in _classic_ would have no effect):
  ...\World of Warcraft\_retail_\Interface\AddOns\BigDebuffs\Retail.lua
• Make sure you save the file after you change it, and then /reload in-game
• If you're using an addon manager, make sure that it isn't auto updating BigDebuffs
