Thanks, ~Watermelon, but I re-checked the warps and all the warps are correct. That's not even the problem because it is warping me to the wrong
map. The weird thing is that all the events are still there. When I walk into a map that is supposed to be a small cave with a couple of sprites in it, it warps me to another one of my maps, but still includes the sprites. They are at the right coordinates but on
another map. And I am warped to what I think are the right coordinates on that other map. I've included another screenshot so you can see what I mean.
Now obviously they are not supposed to be there. Correct events, wrong map. That's why I think it's overwriting something. Maybe like the map header or footer or something, because it looks fine in AdvanceMap.
