Ehm, what da f. So I had tags in my map, worked fine before, added a little part to the single player map for the flood mod, and boom. Doesn't work. So I deleted the tags and tried again. boom, doesn't work. Any help would be great.

One of the tags you're using is corrupted. I suggest removing or changing ALL tags and then trying again.

It worked, I re-installed. Thank you.
