Version: UE5 - Early Access 2
Repro percentage: 100%
I seems to crash every time we try to load a level that has World Partition enabled with the uncooked server. I haven’t tried it with a fully packaged server.
Steps to repro:
1 - Create a new empty project
2 - Enable World Partition in the project settings
3 - Create map with World Partition enabled
4 - Run the game as a server using uncooked content
- UnrealEngine.exe Project.uproject /Game/Map -server -log
I also tried this with the latest version from the 5.0 branch and the crash was still happening.
