Unable to build beds

[Scotty]

Hello!
Its been a while since i have played rimworld so i am unsure if this is a bug.
Right now i am unable to make any more bed of any type.
I have cloth and wood in my stockpile and i have the option to build everything else.

Any posts iv seen that people have asked before has refered to lack of resources.

If you are using the unstable build you have to research them first, hence why there are now bedrolls at the begining instead
