Level built using different engine version

i get this error message : Failed to open map file. This is most likely because the map was saved with a newer version of the engine. whenever i try to open my map, which i had running fine 10 minutes ago, and using same engine version, anyone know the cause?

Hello Juxt4posed,

I have a suggestion that will hopefully get you back up a running while we investigate the issue further and then I have a few questions that will help narrow down what issue it is that you are experiencing.

Suggestion:

  1. Restart your project
  2. Click ok on the error that pops up about your map
  3. Click File > Open Level
  4. Open the folder containing the back up files that are automatically generated (default location: C:\Users\YourUserName\Documents\Unreal Projects\YourProjectName\Saved\Backup )
  5. Locate the most recent back up for the map you would like to open
  6. Open level

Quick questions:

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. Could you provide screen shots of any settings or changes that may be involved?
  4. Could you try verifying your engine? (Launcher > Library> Choose engine version> Click down arrow next to launch > verify)

i got the level working again, it seems that somehow some of my data got corrupted, there was 3 backup files that it happened to, so i just used the back up before that, and no, i cant seem to reproduce it, i will keep trying to though
