"World File Outdated: RUSTRP METRO 2033 V0.3" means that it's trying to load an outdated map.

This could be because of several things. The Custom map was saved with an outdated version of rust edit. Open the map in rust edit after updating your game and save the map again.

Delete the .sav and .map files in your server identity folder and try again with the newer version of the map from RustEdit.
