Nettle Yarn difficulty

[cobaltnine]

Using BAC, I can't seem to spin nettle yarn.  Spinning requests I use wool fibres only.  I reinstalled the game and the mod from scratch and continue to have the error.  Am I missing a step?  I have dried, retted fibres and a very cold PC.

One thing that comes to mind is it could be a mismatch in game version and BAC version. If you are running the latest beta game version then there is only a partly update BAC version available, and it seems it may never get fully updated. See the BAC thread in released mods for more details.
