Cave story + pc holiday sprite toggle not working

Yesterday I bought cave story + for the pc (steam version) and I turned holiday sprites off. When I went back into the game, Quote wasn't holiday sprited, but everything else still was. Has anyone else experienced this problem?

 

Haven't tried it yet, I'd guess it's a bug though.

If you want them off the easiest thing to do is to just set your system's date to, say, the middle of january. You can always change it back once you're done.

 

Yes I have the problem aswell.
How to fix: Go to the options menu, it says they're off, turn them on, and back to off again. Fixed.
Note that you have to do this every time you boot the game.
