Were do your items go if you press the Store button in the inventory?

The "store" option appears if you currently have a chest/container open. It's asking you if you want to "store" any items into the container that you have open.

well [censored] i have no idea were mine is

I don't know what you mean... maybe I wasn't clear though. The only time that I've seen the "store" option was if I opened a chest/container/body etc... and while in the menu I wanted to drop something. There is no drop option, since you have a container open. If I "stored" an item at the screen... it would go to the container that I already had open. So, you must be opening a container of some kind when you're seeing that option. Check the box that's under your nose

no i think it was glitchin up then because it showed a store option while i was in the inventory in the middle of nowhere
