Put the summary of the bug you're having here

What I expected to happen was...:
to be able to craft stairs and the wood block. (the six sided logs) This bug might affect other wooden blocks, but I have not tested them. 

What actually happened was...: 

the crafting recipes would not come up in the recipe book. When I tried to craft them myself, they wouldn't craft at all. 

Steps to Reproduce:

1. Have the materials to make either the wood block or stairs in your inventory
2.  Check recipe book for their recipes (notice it is not there)
3.  Try crafting the items on your own (notice that they will not craft)
