Frozen wood question

[Pituri]

1- Is this already implemented:

This Week: Frozen Wood Veins
Listening to feedback due to the lack of wood in the Null Sector we decided to add a very limited number of frozen wood nodes that can be drilled into with the Ice Borer. This allows wood, without having to trek all the way back out, which is an extremely long journey. We have only added a few so be on the lookout while in the Ice Sheets.

Frozen Wood Veins will provide Frozen Wood when drilled. This Frozen wood then needs to be heated up in a furnace, campfire or any of the heat based benches or devices, this then converts the frozen wood into wood.

2- If it is already implemented, would a world "already" created would have these nodes? Or do I need to create a new world and start from scratch?
