I've been working on a quest for awhile, using a small upgraded NewFirst tileset. Maybe had 5000 combos or so. Well, one day I opened up a tileset that had 50,158 combos in it. I opened my quest after, and now it has to load 50,158 combos on the loading screen, even though the filesize remains unchanged from its previous size. I'm using 2.10v1, but this also seems to happen in the recent builds... any help?
