Hey, you can take a look at :
- [My Solution] “FAILED TO VALIDATE FOR UPLOAD”, “missing a GameFeatureData asset” & related error messages in the Output Log & Message Log
- World Partition/Streaming/HLOD problems in 25.10?
- My map "broke" after today update
My solution was to duplicate the level and use the duplicated level in the GameFeatureData, it decreased the memory a bit.
