still in 14w21b

Sorry for my inactivity, but this is still an issue in 14w21b.

No longer in 14w21b

Put on the boots while you have nothing in your hand then switch to the sword and switch back.

This seems to be a problem in the latest 1.7 snapshots (and possibly earlier releases) but if two items have the same UUIDs but one is armor and the other is an item, if you wear the armor then hold the item and then select a different item in your hotbar both the effects disappear.

These are the commands I used (you will need to put it into a command block):

/give @p 283 1 0 {AttributeModifiers:[{AttributeName:"generic.movementSpeed",Name:"generic.movementSpeed",Amount:0.4,Operation:1,UUIDMost:67664,UUIDLeast:2745}]}

/give @p 317 1 0 {AttributeModifiers:[{AttributeName:"generic.movementSpeed",Name:"generic.movementSpeed",Amount:0.4,Operation:1,UUIDMost:67664,UUIDLeast:2745}]}

Extremely strange behavior when I was testing swapping different tools (e.g. bows, swords, empty buckets) but the results weren't consistent.
Swords seem to be the most buggy especially when swapped with a bow.

Happens with any item (including non-enchantable items). Also tools that were made into stacks with /give.

Here's a screenshot where its a bit more obvious.

Sorry, I thought you were supposed to be able to. Cheers.

I don't understand how this is intentional. Shouldn't the horse be able to move or rotate not be glitched in a frozen position. Please explain.

The orientation of the sides of the blocks is not displayed the same as a placed block with the same data. Damage value 4 displays an oak wood log but the "bark" texture is rotate as if it is a jungle log. (see attachments)

Still in 1.6.1

You need to use a third party editor program. (I used an MCEdit filter called StackEntities by Sethbling)

Thanks

Intended feature

Works with any resource pack. Here's the test one i made (test.zip). Just dump the contents into the resourcepacks folder.
