I logged out and character was perfecty fine.

Next day I logged in and my gun was invisible, I had no pants and my ammo in my Plate Carrier/Ammo box was ruined and showing up as zero stack size (it was 20 rounds when logging off. I had no ammo in my VSS mag attached to my VSS.

I logged out and in again and my pants and gun appeared but ammo still zero size stack {F32990}
