Hi there!
- These errors also happen on a clean project, only with my plugins?
- About the color stuff, did you mean that when you make some change on the font parameter color after you close the game and open it again, it does not change inside the game?
- The delete problem is probably that the game is making a reference for that font parameter, but since the user deleted it, it causes a crash. If you deleted the font parameter, make sure you remove the reference in-game(plugin commands, escape codes, etc...)
It would be nice if you can send to me a sample project replicating the error.
