[4.11 P1] Project conversion fails

Ok, now I got at least a crash message on 4.11 P4:

Assertion failed: AttachedActor->ParentComponent->GetOwner() == this [File:D:\BuildFarm\buildmachine_++UE4+Release-4.11\Engine\Source\Runtime\Engine\Private\ActorConstruction.cpp] [Line: 283]

Interesting note: When I set startup map to an empty testmap, everything works ok. It STILL works ok if I place my BP_Car_Bentley in map (very complex, various child actors). I can also start a PIE session without a problem.

But as soon as I save map, it crashes on next startup.

Deactivating construction script of BP_Car_Bentley completely doesn’t change that.

So it seems a problem of level loading, neither than asset itself (which worked in all previous engine versions).

Hi ,

This was fixed in 4.11, are you still seeing same error? Have you checked 4.12 as well to see if this is still occurring?

Hi there,

any news on this? Still stuck on 4.10 because of this…

Hi ,

you are right. I can indeed open project now in 4.11.2 (didn’t try after 4.11.1).

It also works in 4.12 P5 (but there are new bugs added now which breaks project). I stay with 4.11 for now.
