Title says it all. The majority of the map will load and then this error shows up: Map will still show up after you click out of that error and i am able edit everything like normal except it wont let me save because it says there is nothing to save. I never moved the .wld file out of the world1 folder and i havent moved my data_*** folder or anything. Pretty odd.

Hm...did you remove any .lyr files of your era/game modes?

Okay sorry but i jumped the gun in posting this. At the advice of a fellow modder i took this line out of my .wld file: "TerrainName("CND.ter");" to try and fix an error i was having earlier. Turns out not having that line (even though i have terrain disabled on this map) caused this error. Solved
