Or... it is complete, and all these new ores are useless?
That's even worse.
The impression that I get is that she has a full three tiered design already planned. Because of this she added the ores that will be needed for higher levels of the tech tree. She is doing pre-releases of RP2 to do things like track bugs. Personally after playing with the RP2 pipes in their current state vs the BC pipes with the additional pipes mode, I am leaning more towards the BC pipes. However the breaker and the placer/use item machine are great. They are a good tool to add if you like building contraptions.
