I tried changing a value in the defaults of the weapon blueprint, save, compile and when I exit the blueprint editor, Unreal crashes. This is the error I am seeing
Assertion failed: ChildCount > AttachChildren.Num() [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.10\Engine\Source\Runtime\Engine\Private\Components\SceneComponent.cpp] [Line: 680]
AttachChildren count increased while detaching ‘WeaponMesh3P’, likely caused by OnAttachmentChanged introducing new children, which could lead to an infinite loop.
I am not sure how to fix this issue. Thanks for your help.
This crash seems familiar to something we’ve encountered before. To confirm that this is the same crash, can you provide the log files and callstack from the crash? Including the machine id will allow us to compare the source context from your crash with the known crash.
Is this what you are looking for?
Machine Id: 13F309424343F2D814818B867D6C8F57
That is the information I was looking for however it does not appear that a crash report was entered. When the black crash reporter window appeared did you click either the “Send and Close” or “Send and Restart” button in the bottom right?
I must not have, I just sent in a crash report now
Your crash still isn’t appearing for me. Can you copy the callstack from the black crash report window and directly paste it here?
The crash report window does not show the call stack but this attached what I get from visual studio.
I have verified that this is the same as the known issue (UE-23366) that has been fixed internally. If you make a copy of your project and open it in the latest 4.11 preview version you should be able to work past where the crash is occurring.
