Hello Adam,

I am currently investigating this issue to see if I can figure out the root cause behind it, but wanted to update you on a similar issue I found.

This blueprint node solved this issue for another user, however it does not explain why it is occurring in the first place.

I also found two other resources that give great rundowns of the PCG system, and while they aren’t indicative of any changes made on 5.7, they could still prove useful:

https://forums.unrealengine.com/t/how-to-affect-the-pcg-in-runtime-with-blueprint/1146953/7

I don’t see any issues similar to this on the public issue tracker, but I do see there’s many commits related to PCG that are not yet in 5.7.

CL 47218141 (5e67ed9) and CL 47218476 (6874121) could be worth checking out, amongst the many others I see.

Let me know if any of this helps!

Thanks,

Kyle B.
