Hi ,

Could you post a screenshot or a test project showing exactly how you are setting up the Struct and the AddElem section?

Hello, TJ.
I have attached screenshot and zipped project.
To reproduce this issue you need to add elements to MemberVar_6 than MemberVar_5 than MemberVar_4 and etc.

That you for the additional info. I was easily able to reproduce the issue. I’ve created JIRA UE-20381 for the issue and our developers will be investigating it further. We will post here with updates as we have them.

I don’t have a workaround at the moment, this was also an issue in 4.8.3 as well.

Cheers,

TJ

Hello, TJ.
Honestly speaking I have refused to use 4.8 cause there are much more bugs than in 4.9 or 4.7.6.
The workaround is simply, just doesn’t add an element from end of a Structure BP. It is work fine if an element is added to a first array then a second array and etc. Hope this workaround will be usefull for someone in future.
Thanks you for support.
