Removing loot from too high of loot tables?

So I used the better loot plugin to increase/modify the amount of loot available. After doing so it came to my attention that the loot was way way too high and needs to be reverted. I reverted the loot tables etc but I need help in figuring out how to remove the loot that was spawned during this time from all player's chests/ inventory. Is there an easy way to do this or do I need to go to every chest and do it individually?

 

I'm not aware of any method of doing this. I would look at your connection list and just jump to each player. As your players have spent time looting, I would advise offering them something as a token of good will.
