oh， My deal God！ Who can save me. I encountered the same problem. This seriously slows down my work progress.

Just exactly the same problem above!! Even not neccessary to paste the error log again.

I noticed that the bug code has been pointed out, so when will this issue be fixed?? My suggestion is ASAP!

■■■■! I noticed that the latest unreal engine on github dev branch has been fixed, what a suprise!

So here is my question: When will this feature be established?
And here is the answer: ASAP!!!

I Checked HLODActor.cpp in Epic’s Git.

That code was changed.

check(!InHLODComponents.IsEmpty()) → AActor::Modify()
