No, no errors when the game loads on it's own, nor with "Constants" loaded. I'm at a complete loss for whats causing this. I've redownloaded both strive and your mod, and tried setting it up and its still happening. Also, if I take the vanilla 'mainmenu.gd' and replace the one from your mod, I can load a save or start a new one, but then I get more errors once loaded. Never had this sort of problem with either 6.3.7 or 8.1 of your mod, so no idea why its acting like this now.
