Bug is still present:
Last time this occurred I mentioned it in this post: Lots of bugs. Need help... (with short video) - Programming & Scripting - Unreal Engine Forums
I’m not sure if these bugs are related. I can not reproduce it. It happens somewhat randomly (often after copy-pasting nodes from one Blueprint into another (like from the child to the parent blueprint). But not always.
Also happens after modifying a struct (does not occur in blank projects).
