mh: heh, I'd never noticed. I guess I'd always saved in a near enough to horizontal state.
The error is actually worse than just leaving you looking straight forward: it's -1/3 of the correct angle: if you're looking nearly straight down when you save, you'll be looking up at a bit less than 30 degrees when you load.
Anyway, issue confirmed and fixed* in QuakeForge. Thanks for the heads-up.
*Not yet pushed due to technical difficulties with the git repository on sourceforge
