Does this work with the current version?
And does it just increase amount of stuff transported between your own stations in same sector, yes?

Looks like this might just need a version bump in dependencies - consider

{id = "Avorion", min = "2.0", max = "2.0.*"}

This is working again and happily-supplying my factories with large volumes of in-system goods. Huzzah!

Difficult to say. Again, the logic should work, but I am not able to get factories in an existing save to use more than 20 shuttles at a time. Additionally, it's hard to tell if the out-of-sector logic for cargo transfer actually works. In-sector, the game limits the goods transferred to to the size/volmue of the shuttles, so I've been using another mod that increases the size of cargo shuttles to do the trick, and it's been helping quite a lot. Out-of-sector, the game is just supposed to use the amount calculated (which I increased in this script) and teleport them between factories every certain time period, bypassing transfer between shuttles.

Any word on whether this works? Super annoying to set up production chains at the moment.
