Been doing a run with this mod for a few days now and would like to try it out on the 2.1 branch if you would be able to update it, thanks!

This may also warrant consideration of what 2.1 did to asteroid reprocessing; https://forums.factorio.com/134095

[space-age] Disallow quality modules to be applied to crushers with asteroid reprocessing recipes.
[space-age] Increased asteroid crushing asteroid chunk yield from 20% to 30%.
[space-age] Increased advanced asteroid crushing asteroid chunk yield from 5% to 10%.

[space-age] Added separate recycler mod.

Reworked recipe categories: added hand-crafting and removed basic-crafting, recycling-or-hand-crafting, chemistry-or-cryogenics, pressing, crafting-with-fluid-or-metallurgy, metallurgy-or-assembling, organic-or-hand-crafting, organic-or-assembling, organic-or-chemistry, electronics-or-assembling, electronics, electronics-with-fluid and cryogenics-or-assembling; instead using multiple categories per recipe where applicable.
Moved "recycling" recipe category from base mod to recycler mod.

I will update it for 2.1 in a few days, working on a fix for the Space Tile issue currently, I don't know how I am going to work around it yet though because tiles are hard-coded to not allow quality, even placing uncommon concrete and picking it back up reverts it to normal quality.

Fixed the Space platform foundation issue, I will update to 2.1 in a few days
