Jeez, yet another problem.
So i noticed today, after downloading some maps, they crashed. Thought it was due to the game update or that some .fho's were the cause. After deleting EVERYTHING expect the .fhm file, it still crashed. Meaning, they are broken. Not only that, now i tried to go into map maker and that crashed at me the second i clicked.
I'm guessing some of my files are broken? I can't think of which, as i didn't touch any files in the terrain folder expect for the textures.
