I would love if lootbox could store a chest assignment, rather than the loot data itself, then empty/remove the chest being clicked on. I also realise that's probably super difficult to get working, potentially require a rewrite of the entire looting system and would take far too much dev time for a silly item barely anyone uses.
For example instead of someone right clicks a chest then everyone nearby with a lootbox gains x currency, x items, x filler blocks and x potions, you get 1 share that is something like "R2_Purple_12pts_4players" storing no data itself except the chest type that was opened, then when you open the stores it'll roll the chest that's been assigned to it (divided by the number of players), and idk if the limit is in place already, but you should really only be able to open say 10 shares at once to further prevent bans
