[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 there,

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

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 ,

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.
