I've been testing the Medkit and the Feat on my crew until I had to use on my because of my health.
Medkits mechanic is ironic. I could save others from death but not myself.
After testing the Feat, it consume the whole Medkit and make it "repairable". This is the bug I want to report. You can't fix it on the Mortar as it says or anywhere else (Looks like it doesn't recognise the resources)
