I have the updated version of the mod + forge and I am on single player creative mode. For some reason I can't make or find certain items (Carpenters bed/door/garage etc). They aren't in the creative inventory and I'm not able to craft them. The only items I can access are the Carpenters blocks, hammer, chisel, slope, and collapsible block. It seems like no one else is having this issue but it's happened to me before with other mods and I can't figure out a solution.

Are you talking about the POC 1.12 version? That's not an alpha or even beta release and is missing most things.
