Getting a crash with this error, on the most current version of the mod:
Error while running event concreep-redux::on_nth_tick(600)
LuaEntity doesn't contain key ghost_quality.

Not 100% sure, but it seems like it's having issues with placed ghosts for Agricultural Towers - which is odd, considering that none of those ghosts are actually in range of any of my roboports yet (specifically because I didn't want the area paved over before I get the towers in place).
(EDIT: As a stopgap, I disabled concrete placement on Nauvis, and it seems to have solved the problem. Also, looking at it, it does look like a couple of the ghosts are placed so they are just hitting the edge of one of the roboports, so... yeah. If you need any more info, let me know.
