Yesterday I was working on a prison map. In total created around 50 objects. I saved the map, went to bed. Today I attempt to load the map, and there appears to be no objects at all. Infact I tried loading any map (even the pre created maps) and none of them had any elements. I then tried to create a new map. Placed 1 object and attempted to save it. It just sat there and didn't do anything. So it would seem there is nothing wrong with the files themselves but rather MTA. I find it weird that it can work one day, but not work the next day. Has anybody experienced any such problems? Or does anybody know why this might be happening? EDIT: When I pressed F5 to go into test mode, I got this error...
