Forge log link:

Problem: Mining a naturally-generated Dark Ore with a Silk Touch pick drops a ore item with a broken texture/model. This happens when mining them both manually (regardless of the pick used, can be replicated with vanilla), or with a machine like RFTools' Builder. Manually placed ores (given through creative tab, or through JEI if installed) don't seem to have this issue. As a note: besides this visual glitch, the item itself works properly.

This can be replicated on a clean instance with only Forge, CyclopsCore and EvilCraft (like the one used for the log above).

Expected behaviour: The ore not to have a broken texture.

Steps to reproduce the problem:

• Create a new instance with only:
  • Forge 2259
  • CyclopsCore 0.9.4
  • EvilCraft 0.10.21
• Open a brand new world, default generation (also affects others, like ATG; mentioning it just in case)
• Search for some natural Dark Ore
• Mine one normally, no issues there (drops dark gems as expected.
• Mine one with a silk touch pick, get an item with no texture.

@starg09 Is this occurring in newly generated chunks? Because the bug was caused by invalid blockstates during worldgen, so any previously generated chunks will still have the problem.

Seems like this still happens on release 0.10.22 for MC 1.11.2

Strange, I tested this right before the release, and it worked just fine then.
Maybe I did something stupid, I'll look into it.
