Falling through map "aware this is a known issue" just want to explain some reproduction steps.
Nvgs while not using but keep battery in nvgs will continue to drain battery but won't visually show drained will only be aware battery dead once remove battery to hand, inventory or ground will it show battery true life status remaining "this bug has been a thing forever"
Gun in hand, plenty of space in inventory, hold "Y" on Xbox will not replace empty mag in gun with another mag in inventory albeit mags in inventory have ammo in them, this is catastrophic in a pvp situation when can't get another mag in gun to replace existing one but bug can happen anytime anywhere any situation. "Long time bug"
Will add other comments when can remember other bugs my memory fuzzy at the moment but sure I'll remember more.
