[Outdated][Bug 1.19 Steam] Slots sometimes stuck waiting for incoming item

I’ve experienced several times that one of the fit-slots can get stuck waiting for an import that will never arrive.

Destroying the slot and replacing it with a new one will make things flow again.

This happened with one of the ‘fit doors’ slots shortly after loading the save file attached in viewtopic.php?f=57&t=18669 - but I don’t know if it is reproduceable.

I want to report that this is something that occurs now and then - I’ve probably seen this about ~12-14 times during the game in the referenced savefile.
