Hi,
This one is a bit hard to reproduce and to diagnose, but I find that copying and pasting station blueprints does not always work. It manifests as a "ghosted" station, even though it has items to provide (I'm not sure if it happens on receivers).
Saved game is here:

The game has been sitting there in this state for about 30 minutes (which is not really relevant, but I thought I'd mention it, just in case). The adjacent copies of the same blueprint were pasted and built just before, as a "batch" of six, but they do not show the effect; they're working fine.
