(Apologies beforehand if someone has already posted something about the Frozen Dirt or related) As you can see from my screenshot included whenever I go to place Frozen Dirt it places a Wooden Platform instead. I'm not certain if this problem is just my end or not. I've tried verifying my files on Steam and it still persists. It isn't major game breaking bug, so you don't have to make it a major concern, it was just something small I noticed and would like to inform you about.
This will probably be fixed in another Nightly. It happens, you know. Chucklefish made a typo when they made a new matitem file for the new material. I'll report it in IRC.
