Whenever I try to scrap items I will literally lose half my inventory. Scrap one helmet I dont use and then 500 materials worth of armor disappears. Scrap some ammo I dont need and there go all my guns. Super frustrating. This feels more like a beta.
That is either a bug, which an be reported with F12, or you are scrapping all of them at once
I already reported as a bug, happened in bb5 too. Wanted to see if anyone else had that problem. I scrapped some leg armour I didn’t need last night and most my heavy weapons disappeared 
Used scrapping several times, didn’t notice anything missing.
