My inventory is disappearing on my character when i log back in i cant figure out what or why its doing that anyone have a clue.

Which game? IF it's ARK, it sounds like you have a beyond "slot capped" inventory, which typically happens when you're slot capped, and have food spoil, which can cause a corruption of a profile. Your best bet is to have another player try to access your unconcious body and see if they can see items on it.

Otherwise, you'll need to roll back the profile at best, and wipe the profile at worst.
