It basically wasn't turned on. The code for steele preg is somewhat complicated and there were some things needed for kuitan preg to be fully functional that had not been done yet. It should now be working.
I hinted to the team that as the preg specialist they should get me involved whenever someone codes preg, even if it is just to look it over as a second pair of eyes. It is easy to miss one of the little fiddly bits that are needed.
