So, I don't know if anyone else has had similar problems, but it seems that my
The Bat's Mouth pattern set is causing some weird lagging issues with my game. I haven't discovered yet if it's the entire set, or just a few of the patterns, but I'm currently looking into it in order to get it fixed.
Frankly, I have no idea how patterns, of all things, could cause the sort of lag I'm seeing, but since they are, I wanted to give all of you a head's up. I'll keep you updated on my progress, and let you know if I end up with fixed versions. In the meantime, it's probably best to take that set out of your game just to be on the safe side.
Sorry for the trouble!
But good luck fixing whatever it is.
