Regardless of settings, AmmoLoaders seem to be unable to hook onto Entities that aren't on the default planet.
SpacePlatforms, other planets.

The only way I could get the Loader to load turrets was to change a setting midgame while my camera is looking at a turret for it to suddenly see them.

There is also the cross instance setting that I tried but that didn't work for very long and tended to stop working. Is it possible that the way the chest detects things to load is not working with the new Instances system? I don't have a log to share but I can share my save.

The issue became unfixable when I made a second space platform and uh...getting destroyed by rocks is funny but definitely not ideal.

To be clear if it's not obvious with my wording: The Loader won't work even if I place one in each new planet or space platform. So I'd have to go back to loading the turrets by belt if it's not on nouvis. Not sure why that is the case.
