Map loaded but loading screen won't disappear

Hi, I'm currently having an issue where the map will load, but the loading screen will stay stuck. The only way to look at the map is to hit F11, but once I leave the world editor the screen comes back. If I hit esc while the loading screen is stuck it will bring me all the way back to the main menu while the map is still running causing the game to become very unstable. Is there any solution/reason for this bug?
