This time there is a timeout warning between the warm up and valkyrie destruction
How did you remove the HLODs, Delete HLODs from the build menu doesn’t have the functionality needed sometimes and in the past has left old references to deleted assets, especially custom ones and certain problems.
The best way to remove the HLODs for a test is to make a totally new HLOD layer in the Content Browser, in your main project folder Right Click and choose World>HLOD Layer
Then go into your World Settings and change your Default HLOD Layer to the new one.
Launch a session and test, if it doesn’t work this way, then its more likely not a HLOD issue.
