The ones that are black are instances created with my construction script (which worked fine in 4.12.5) which is outlined here: Issues with actors' tags filtering in BP - Blueprint - Epic Developer Community Forums
The ones properly lit and with textures (and not missing any pieces) are made same way you made yours.
What am I doing wrong with construction script that causes instances disappear and not receive lighting ?
Thanks
