I found this neat font that I figured I could use for the title screen, but when I insert it and change its palette, it doesn't change ingame: 
I've tried other stages, and it appears that this override is exclusive to C7. I've also tried to simply edit the overworld palette, but I soon found out that said editor only allows 2 colors per palette, whereas this font needs 3.
How do I prevent this override from happening?
