Blueprint with MID's doesn't save properly.
I'm experiencing a crash if my blueprint contains two static mesh components with two different Material Instance Dynamic.
It seems that if you create MID's on your meshes and than save the map, after loading it becomes corrupted. It looks good on the first look but when you try to delete it and than ctrl+z the engine crashes.
This is step by step guide how to reproduce this error.
Error I got:
Unhandled exception at 0x000007FEEC2E0EAB (UE4Editor-CoreUObject-Win64-Debug.dll) in UE4Editor-Win64-Debug.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.
PropertyObject.cpp line 38:
Property that crashes: "OverrideMaterials"
Is there any workaround that we could use here? And most importantly, why this error occurs?
