I think I've identified a bug that explains how I've lost more than a few on-foot materials from the storage in my Fleet Carrier.
If you have material(s) stored on your carrier but have 0 units of the same item in your backpack/ship, the UI doesn't work correctly. Instead of transferring/discarding the item you've highlighted, it processes a completely different item. For transferring this is easily detectable because the numbers for the item you're trying to transfer won't change (and if you hunt around, you can find the item in the list that will actually be transferred), but for discard mode it's not - the game will just randomly discard something else. Imagine you've spent hours battling RNG to gather a certain amount of materials only to find they've mysteriously vanished into the void....
Here's a couple of screenshots explaining what I mean. In the first, I've tried to queue a transfer of 6 Compact Library from the FC to my ship (notice I have 0 units currently on the ship, and let's just ignore the IONISED GAS multiple entries bug and lack of alphabetical sorting for now):
I know, it looks like I haven't done any such thing but I can assure you I pressed the left arrow 6 times. And the CONFIRM ITEMS TRANSFER button is pending. But so is the ASSETS tab - let's see what's going on over there:
Those are what actually got queued for transfer - 6x chemical catalyst. I have no idea why it picked those, except that I have some of them on both the carrier and my ship.
This situation is obviously a lot worse if you're in discard mode, but I didn't want to attempt gathering demonstration screenshots for that because of the risk.
TL,DR; don't transfer all units of any material to your FC until it has been confirmed that the UI has been fixed. Otherwise they are stuck there forever with no way to transfer them back and discarding them risks trashing something completely different instead.
