Hi I have been getting this crash on and off what seemed to be randomly for the past couple months. The other day I accidentally figured out a way to repo the crash 100% percent of the time.
Basically what I am doing in game to cause the crash is I have instanced static meshes that are being destroyed and then recreated. I attached the dmp file below. Code I am calling that appears to be causing the crash is
This is being called on a custom component extending UInstancedStaticMeshComponent. I am clearing all instances on the component and then recreating them based off the ReplicatedTransform array all in the same frame. This works 99.9% of the time, but sometimes causes this crash.
Any help looking into fixing this issue would be appreciated. If any more info is needed let me know.
This is UE-22078, it's in 4.10 but it's fixed in 4.11. This commit fixed the bug: https://github.com/EpicGames/UnrealEngine/commit/e09f279825be41f28d10f94e329e3d6de6efb9c2
