The fancy chisel carpets are not accessible without cheats, is this intentional?
When a chisel carpet is chiseled it is possible to access a third "null" variation of the carpet color. Breaking this block gives the player nothing.
I also found this error in my log file. https://gist.github.com/NotAVerb/7f947f810b8006fef1c1490ff71c59fe

Chisel's carpets are also transparent on their undersides.

This seems no longer relevant
