Hey, just for what it's worth, this was almost certainly some weird mod incompatibility that was causing this - it usually worked fine. Hopefully it resolved?

Now that 1.4 has multi-stack shelves, hopefully this won't be an issue again :)

I am still having this issue on current versions of everything.


EDIT: It seems to be a proximity thing, I have the search radius on the bench at unlimited, but if I move the shelves under 25 cells away (same shelves, just moved) the bench can find them, move those same shelves back further away and it loses them again. This is specifically with the Assembly bench, haven't tested with others yet, but none of the others appear to be hanging up.
