Gooooood afternoon, I noticed that when placing quality ghosts, as long as I have the normal style of the item. It will make it into a higher quality. I noticed this when using rare steam engines and I hope this can be patched to work with this space age addon

So you have a normal steam engine in your inventory, and no rare steam engines, and the nanobots place a rare steam engine on a rare steam engine ghost?

Aye, I just experienced it, and I think in general mod doesn't deal with quality in general.

I placed an energy generator blueprint (solar panel + substation + accumulators + roboport), all items in blueprint were of rare quality. In my inventory I had solar panel of rare quality and substation of normal quality.
I observed that substations were placed by bots, despite the fact that I didn't have rare quality substations, while solar panels remained unplaced.
