I have now changed the version tag from 5 to 6, just in case someone thinks that the version warning when one chooses a pack does matter. In reality, it does not change anything. Every time Mojang changes somewhat the filesystem, like spliting the paintings file in to seperate files, they change the tag. In most cases, the change in the filesystem does not effect the little thing in a simple resource pack. In the case of the paintings, you just splitt the single "paintings" png into each paintings and give them the right name, and it will work again.

I have also added the potions since a found something in the file where it was roman numbers.
