Compact and UPS-friendly 1x1 loaders. Works with train cargo wagons, circuits, filters, and modded belts from Bob's, Krastorio, FactorioExtended Plus, Space Exploration, and Ultimate Belts.
Norfair, are you using miniloaders with Space exploration?
Xeraph, looked into it a bit and figured out why the se-space miniloader allow blueprinting. It came down to SE's collision mask.
You can edit the file miniloader\prototypes\entities.lua.
After line 26 add entity.se_allow_in_space = true
This allow for blueprint but the other issues still exist like copy filter and circuit doesn't work properly.
