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.
Having the same issue after updating. Totally fried several production lines and not sure I'll be able to locate all of the loaders in use that need to be fixed by hand.
Worse yet, reloading the save always seems to revert the loader's orientation. It doesn't always flip it (i.e., I can't log in, get flipped, save, and reload to get back to my original orientations).
