Hi @KetherGame,

I see what you’re saying. It looks to be a [longstanding issue](https://forums.unrealengine.com/t/keep-simulation-changes-with-custom-class/333955). I just tried the workaround mentioned in that thread (Simulate, Select actors, Copy, End Simulate, Paste, Delete originals) and it seemed to work ok.

Hope that helps!
