About this Mod

An unofficial 1.20.1 backport of Actually Additions, a tech mod.
So far, all features have been ported over. Several include:
- The atomic reconstructor, used to turn resources into crystals.
- Machines for automatically doing stuff, such as the auto-placer for automatically placing blocks, auto-breaker for breaking blocks, and the farmer to farm. In this port, the auto-breaker can utilize the top-left slot to break blocks, if a tool is needed.
- The empowerer for empowering crystals into their empowered form.
- Canola for oil production, which can be a powerful source of energy.
- Lasers for logistics, allowing transport of energy, items, and fluids.
- And much more.
DO NOT REPORT ISSUES TO THE ORIGINAL AUTHORS!
ANYTHING THAT BREAKS IS MY FAULT, NOT THEIRS!

I did not make this mod, the original author, developers, and artist did. I simply ported it to 1.20.1.
