Custom maps from world builder no longer load.

[Vladimir Lemon]

I've seen multiple posts on here with the same exact problem with no solutions, so here's to hoping this issue can finally be solved. I've made a ton of custom maps using the SDK's worldbuilder and up until recently loading my custom maps in game would be no problem. I don't know exactly why this started, but when I tried loading one of my maps after modifying it in the SDK I would get the eternal loading screen and have to close the game. Initially I assumed this may have something to do with mod dependencies (I figured I'd accidentally saved the map with mods enabled) because when I attempted to load the map in vanilla nothing would happen. I found that rather odd, because my maps would always work fine with or without mods. So I tried loading it up through the mods menu but to no avail. It seems regardless of whether or not I load in vanilla or with mods, the map is just broken. So I then decided to disable all mods, load up the SDK, and save the map without any mods enabled. I could get into the map on there just fine so I made my modifications and tried loading again in game which proved to be completely fruitless. Abandoning my initial plan to try to salvage my maps, I decided to just make a new one in the worldbuilder and save it, this time going as far as reinstalling the entire game, SDK, and deleting any remaining mods I might have. I then tried to load in both the mod menu and vanilla, and the same thing happened. Something of note that I found interesting was that any maps I had not modified but were still custom maps would load perfectly fine in both vanilla and modded games. Needless to say, I'm completely stumped and desperate for answers. I'd be grateful for any help.
