Howdy. When copy-pasting loaders connected to storage and belts, they sometimes don't orient properly.
Setup
- Create a few warehouses, red belts and red loaders.
- Equip armor with a roboport and have some construction bots.
- Import this blueprint string:

Reproduction
Place the blueprint. Test that items move from the top warehouse to the bottom warehouse and the bug (below) didn't happen when placing the blueprint.
Now, copy what has been placed in the Factorio world with CTRL-C (CMD-C on Mac) and place it a short ways away. Observe that the loaders are not oriented correctly. In fact, rotating them doesn't fix them--they must be replaced.
