Bug Report? Child Blueprint keeps dropping

I’m not sure where to report this or if I’m doing something wrong. I have never had this problem in versions prior to 5.6.

Its hard to describe and the only way I could show you is via video.

I have a Main BP that runs my game. I created another BP that is placed on the main BP and it is set as a Child Actor Component.

If I make certain changes to my overall game, its like the Main BP losses the child connection to the BP and it doesn’t load properly at startup. More importantly, all “expose on spawn” are not being populated though the actors do show up.

I have to go back to the main BP, click on all the actors and re-select the Child Actor Component. Once I do that and recompile everything works fine.

At first I thought it was only happening when I made changes to the BP that is being added, however, I just added a new enhanced input and it did it again.

What is causing this Main BP to lose its connection/tie to the child? I have a bunch of other BPs setup the same way and this doesn’t happen to them. This was a BP that I duplicated and reused but there is nothing conflicting name wise or anything else.

Ok and now this just happened. In trying to see if maybe “resetting” it would correct it, it crashed Unreal Engine instead!

All I did was click on the “reset to default” next to “Child Actor Class” and Unreal crashed hard.

I just lost a bunch of work and when it restarted it said it had restore/save points but then said it couldn’t check them out of the repository and couldn’t restore them……

Update:
Ok - I got everything working again. What apparently caused the crash was I accidently assigned the same button (right trigger) to two events in IMC_Default. I was getting all sorts of weird “class call” fails and other bogus stuff. This shouldn’t have crashed UE and caused all this weird stuff. I fixed the input assignment and everything is working again… but the crash is unrelated (or not) to the initial problem which is why does this keep losing this child component assignment?

I’m still having the same initial problem though!
