Productivity in beacons? That's ... unusual!
I use the "productivity in beacons" mod, but hat was just an example. It could very easily be 10 Beacons with Speed Modules and two with Efficiency Modules. Or any other combination of modded modules. My issue right now is that all modules on the same line have to have the exact same inventory, because each line has only a single entry for beacon inventory. This works for a smaller number of Beacons, but starts to break down with 12 or more.
I'm experimenting with larger structures which can support up to 20 beacons, and those start to cap out production stats regardless of what I pick. It's not easy to tile, but that's an issue for me to solve while building it. I'd like to know if it's actually worth doing before I start :)
Thank you for having a look, regardless. If Helmod already has an option for it, I'd love to use it.
