This is in regard to a question that came up in the discord chat.

When using ContentTweaker, B.A.S.E, and Chisel and bits, you experience some graphical issues.
When Chiseled, Blocks of metal go to the purple and black unknown texture, and ores go to their base material, both with atint overlay of the ore they had on them.

For example, here is a screen shot of Block of Copper and Copper Ore. The bottom blocks have had one bit taken out of them.

After regenerating the models, normal blocks work. The only thing still not functioning properly (at least related to the two examples) is the ore.
