Solved Players with insane amounts of items

Hi I don't know why but after the recent xp update I have found numerous amounts of players that have large amounts of items. I have never had this problem before and gather rate hasn't been changed. Is there some type of dupe glitch with this most recent update?

 

I have found the problem it is to do with BetterLoot, it changes the bp of the item into an enormous amount. ie bp of rocket results in 444 rockets
