[2.0.14] Items sent to space platform disappear

[Orum]

I'm trying to construct a new space platform, and I'm manually loading rockets with what is needed. These rockets can be either auto-launched (as "Auto request missing construction materials" is checked) or manually, as presumably they aren't perfectly full. The materials show up as "On the way" in the "Space platform hub" window, but then never arrive, and just vanish.

Some times all of the items vanish (e.g. when sending 5 rocket engines they all disappear) and other times just a few of them vanish (e.g. I sent 4 solar panels and 8 accumulators in one launch with some other items; I didn't keep track of the other items, but only 3 solar panels and 3 accumulators arrived).

This is repeatable, as I've now sent up 10 rocket engines, none of which arrived (saving before the second launch of 5), then reloaded my save and sent 5 again, and still, none have arrived.

Edit: Just wanted to note that this still occurs with 2.0.15

Maybe you can post the save ?

[Orum]

Oops, sorry. I meant to do that in my original post.

Just drop the 5 rocket engines into any of the silos, and they will auto-launch to supply the "GSE" platform (but never arrive).

All the stuff was delivered. However, you have some unfiltered inserters taking it out of the hub onto belts.

Ah, I thought things were supposed to build instantly (as long as there was platform below them) so that this wouldn't be a problem, but that seems to not be the case. Thanks.

Also happens with modules, so they make a third layer: first the platform, then the building, then the modules inserted into them.
