help please

its blueprints only, if that have any effect

im now trying to fix it by removing “map12.umap” tho i would love to know what corrupted it, it’s not funny to use hours to build a map and then have it corrupt for no appear reason, i dont remember making any changes on it since the last successfull build

and fixed, but question remains, what happend to my map :frowning:
