I set min items 10, max items 20, I set items which I want in drop but it only gives 8 items every time.
Any ideas?

Once file is edited and save in oxide files config open up your console and type to reload plugins and configs of plugins  :    oxide.reload all

also drops do not disaperiing after emptied :( and sometimes I do get empty drops to

I'm having the same issue. I can specify min/max but rarely is that respected. I have removed randomizations: 

UnityEngine.Random.Range​

 

I hard coded an Int I wanted to validate and regardless of the Int returned or specified, BetterLoot spawns the incorrect amount of items. I would think if I spawn a min/max of equal value I should see that reflected, but maybe I'm missing something or other behaviors are at play.
