Dank Null Version:1.6.77
p455w0rds Lib Version:2.2.156
Forge Version:14.23.5.2846

Steps To Reproduce:

1. Put item with stack size of any odd number below item's max stack size. (1, 3, 5, ... but for enderpearls, snowballs, eggs, and such must be less than 16) into dank/null.
2. Right click item
3. Profit

Note: I believe this is caused because Dank Null rounds the stack size up when right clicked, as well as the items left behind being rounded up. Therefore, whenever an odd stack is right clicked, one extra item gets added to the mix.

Was this tested on Single Player or Server (or Both)?
Server.
Was this tested with just Dank Null installed, if not what is the minimal set of mods to cause the issue?
It's a Dank only issue afaik, would be pretty weird if some other mod caused your mod to dupe.

its a feature
