The bug

The Iron golem's texture contains several textural errors:

• The left hand uses a placeholder texture, unlike the right hand
• Another placeholder texture can be seen when moving into iron golems
• Instead of fading to brown and then suddenly becoming metal again, the feet should be completely brown
• The bottom of the lower body should be more detailed, like the bottom of the upper body
• The left and right arm should be switched, because currently the left arm has vines disconnected from the other vines, and if we switch the arms all vines are connected

This is the current texture, this texture fixes these problems. It also removes all unused parts in the texture.
