Bug Report

When you lock a framed drawer with the appropriate key, to make sure its content type do remain even after being emptied; if you unlock the drawer, then shift+right-click to force a reset, the server gets desync with all the clients around.

This can lead to many issues when moving items around (client-side only duplication bug, items not really moved, not really in inventory, etc), and players not seeing the same thing.

Expected Behaviour

When unlocking a framed drawer then shift+right-click on it, it should get reset correctly and for all players connected.

Possible Solution

A workaround is to make sure there are still some items in the drawer, unlock it, remove the items, then lock it back again.
If you got into a major desync, the only solution I found was to restart the server.

Steps to Reproduce (for bugs)

1. Get multiple players on the server
2. Build a framed drawer
3. Build a drawer key
4. Put an item in a drawer
5. Lock the drawer with the key
6. Take all the items from the drawer, the item icon still appears since it's locked
7. Unlock the drawer with the key
8. Shift-right-click on the drawer, it opens the UI, and the icon disappears but only for the active player (other players still see the item icon)
9. Put another item in the now "wrongly unlocked" drawer, it disappears from your inventory (but not really, it's still there), and looks like it's in the chest (but it's not).
10. All clients are now desync and many issues will appear with the drawers
