Twigs and Quark blocks with identical names transform into each other

[JediMB]

Describe the bug
When harvested, Twigs and and Quark blocks with identical names will sometimes transform into each other. This has been observed with Polished Calcite Brick Vertical Slabs transforming from their Quark variants to their Twigs variant, and Polished Calcite Vertical Slabs transforming from Twigs to Quark.

To Reproduce
Steps to reproduce the behavior:

1. Place the specified blocks in the world
2. Harvest them with a pickaxe
3. You will often (but seemingly not always) get the other version of the block instead

Expected behavior
Blocks are obviously expected to stay as the variant you crafted to begin with.

Info (please complete the following information):

• World Type: Server
• The_Vault Version 8.0.3

Additional context
Not sure if there's any interaction, but I have also been crafting Polished Cut Calcite blocks through the Stonecutter, and apparently those are only supposed to be craftable after researching Create, which I haven't done yet.

Not an issue with the Vault Hunters Offical Modpack. (issue with quark and twigs)
