So yeah, just to re-iterate, since I’m getting no response on this, I tried to port my 4.13 project to 4.15 (and now 4.16) and it’s broken. I have a function that called Add Child Actor Component. When I make children of that blueprint, the actors it spawn do not match the ones I am calling in the base class. The result? I now have buildings and rocks spawning in the middle of my street because I guess it thinks they’re trucks now? Anyway, I was hoping t0 upgrade my mobile game to improve its performance with all the upgrades added to unreal since 4.13, but this is a major blocker. I’m stuck until this is resolved.
