Child Actor component weird behaviour in PIE


so i’ve originally started topic on answerhub, but it looks like it has been buried. Here is the topic: Why is my Child Actor component causing a crash? - C++ - Epic Developer Community Forums

In short, if actor has Child Actor component, editor most likely to crash after second blueprint compilation during blueprint reinstancing; also while playing in editor, it spawns second instance of actor for each Child Actor.
Little bit more info including call-stack on crash in answerhub topic.

Thanks in advance, i’d appreciate any help, currently this issue stops me from further work.

Posted in C++ section as it was originally about implementing component based on existing actor.
