1.2.2 update:

*Added 2 new pottery sherd variants, both of which can be found by visiting certain structures from this addon
*Zinc golem spawn egg is now found alongside the rest of the vanilla spawn eggs in the creative inventory
*Using a zinc battery on a deactive lightning box will no longer consume the battery if you're in creative mode
*Brass/copper chain and lantern have been improved and now work similarly to the vanilla chain and lanterns
*Improved the zinc zinc zinc disc to make it more like vanilla discs - playing it will display the song name at the bottom of the screen and taking the disc out of the jukebox will actually stop the song
*Improved creative inventory item placements of the blocks and items of this addon
*Enabling the addon will no longer disable achievements, as long as you're not playing with cheats or creative mode
*Fixed all of the blocks in the addon not being compatible with redstone - they previously couldn't conduct it or have redstone be able to trail up/down
*Fixed Brass door open and close sounds being too quiet
