Wasn't a fan of having the ability to use upgrade modules in asteroid crushers removed, so I added it back. It's now locked behind end game technology(s). It is unlocked after Promethium science packs are researched, giving one alternative to the packs than just research speed. Alternatively there is a mod setting that you can set to make it only 30k of each science pack EXCEPT promethium, meaning all packs up to Cryogenic.

30k of the science packs, 120 seconds processing time.
