I am not sure what this error means. Suddenly if i open a certain map the editor will crash with this data displayed. Any ideas or help would be amazing as Iā€™m not sure what to make of it.

sorry if this is posted in the wrong place.
everything else works great so this is a mystery right now :slight_smile:

update: the map in question also crashes the editor when right clicking the file in the content browser.

update 2: I fixed this by taking a backup of the .uasset and then renaming the file in Project/content/ to .OLD and copying in the backup.

I would still love to know what happened / what i did wrong. Archived the broken file.

Hello MushroomFleet,

After looking at the call stack and doing some digging I found that this is a known issue. I have provided a link below to the original thread. It appears to be an issue involving a null value for a light component in your level. Please feel free to add additional information to the link provided and to visit that link for future updates.
