Another question, I was looking at the COMP/CON program and noticed there are some frames not listed under their manufacturers in the book (Lich, Kobold, Zheng, Atlas) are these in supplements or am I just overlooking them somewhere?
What the other person said. Each of those (collectively the "Long Rim Mechs") also just got updated on itch.io, though, and Comp/Con hasn't yet been updated to account for those changes.
