I went to load my new map for 17 today and it would not load because the game said something about a CRC check error...no big deal i'll just use one of the auto saves...
except they look like this

Everything seems to function fine, it just looks like garbage.
With some experimentation, I found that if i place stone bricks down on one of the trouble areas and then remove it, it fixes the issue, but only for that one spot.
Is my save file just trash or is this fixable?
