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.
Just updated to 1.15.3 (didn't note my previous version unfortunately). Miniloaders placed prior to the update work fine, but newly placed ones will only output on one side. Using the copy/paste entity settings from an existing working one will cause the broken one to start working
Missed the item in the patch notes, looks like this is a new feature. Perhaps it could default to configuring both lanes at once as the default to match previous functionality?
