[Bug?]Split structure members in BP function library then modify this structure cause crash

Development Programming & Scripting

Hello Epic,

I am not sure it is a bug, or just not allowed to do like this.
Reproduce this crash is simple:

1.Create a structure Struct_Test.

2.Create a BP function library BPF_Test, add Struct_Test as NewFunction0’s input and split its members.

3.Create a GameMode BP_TestMode, asign it as override game mode. And call NewFunction0 when EventBeginPlay.

4.Open Struct_Test, add new member into then crash happens.

PS: I don’t know since when the structure pin can be spilt and it’s great helpful!

And this crash seems only happend in BP function lib.I can avoid it by some tricks, it’s no big deal. I am just worry about the reasons cause this crash may do more serious harm.

Hi xiuxiu,

Thank you for the report. I was able to reproduce the crash in 4.8.2 but it is now fixed in our latest internal build. You should see it working properly in a future update.

Cheers,

TJ
