This would only be a minor annoyance if not for the fact that crafted ammo prefers to go into your ammo slots if it's a match. So here I am, driving my tank, crafting ammo that I want to put in the tank, and it's disappearing. I can't retrieve it without getting out of the tank
Also, I can't get to my armor to disable my personal roboport while I'm driving.
Well, even if the interface problem is a missing feature, the crafted ammo disappearing strikes me as a bug. It should go to your inventory if you can't get to the ammo slots, I think.
