I have made some textures for Harru Labs and I discovered that the texture for the snowman pumpkin head is flipped, making putting writing on pumpkins kind of awkward.

-Steps to reproduce:
Put a letter on the pumpkin texture.
build a snowman
see texture is flipped.

as a final note. Nothing other than the texture pack was changed.

and now. how about some pictures?

the first is a pumpkin on a block of iron
the second is a snowman with the pumpkin head
