Guess what asshat, I just checked.
There was zero development in WFRP (1986) - the Lizardmen are troglodytes and the Slann are nowhere to be seen in the book (half-squatted already). What's there is copypasted from 3rd edition WFB.

The Lizardmen/Slann combo we know today?
ALL OF IT comes from 5th FB, invented in the year of our Lord 1996 by Rick Priestly with zero involvement from the WFRP people
