 Description   

Items in inventory do not stack consistently depending on if they were created before or after when you last logged out or did a Save and Quit.

Steps to reproduce:
1. Name a block of dirt "A" using the anvil.
2. Name another block of dirt "A" and see that it does stack with the first.
3. Save and Quit then open the world again.
4. Name a third block of dirt "A" and see that it does NOT stack with the first two.
5. Save and Quit then open the world yet again.
6. See that now all three blocks of dirt stack together correctly.

It works fine for me. I assume it's only an issue because of modified server software (e.g. Bukkit/Spigot).

I am still experiencing this bug in 1.12 on play.wildcraftmc.com

for some reason, it does work after a while, I'm not sure when, but I sucked an item up in a hopper then dropped it again using a dropper, then they did stack.

Confirmed and voted.

I can confirm this bug for 13w06a. It's really annoying for item sorters. I also noticed the NBT data is just the same.
