Hi, before 2.0, quality modules weren't an issue because upgraded construction robots didn't scale that much. But now, with combustion furnaces made only in supermagnets, it's really a bummer that you can't use quality modules. I'm not sure if this is intended or a bug. If you want to prevent extreme quality bonuses, you could consider adding a built-in negative quality bonus to offset the large module slot.

It's intended because in order to prevent the breaking of other recycling loops, you can't recycle any intermediates of anything on Vesta. It's less about preventing extreme quality gains and more about preserving the game's internal loops.
