Since the update on Oct. 3rd I've had an issue where I would loot an item from bradley, heavy scientists, elite crates, or heli and it would not stack correctly with my stacking plugin. I was using StackSizeController as well as Magic Loot. The issue I had was items would not transfer over, almost like it was phantom loot. I'd have a C4 in my inventory, loot a C4 from bradley, and still only have one C4 in my inventory, losing the second C4. After unloading Magic Loot I would have no problem with looting or stacks, so I know it is MagicLoot causing this issue. 

 any update on fixing this?

None yet that I know of. I switched over to using SimpleLoot since I'm only multiplying the components at the moment. It's only a temporary fix until MagicLoot is updated

Any solution to this? Just got this problem, dont know why, i have had MagicLoot and StackSizeController for a while now. And i'd really hate to use an other loot plugin

i fixed i just deleted my config 

Same here. Deleted my config. This problem started after i edited the individually loot containers in the config.
