Running Steam version of Warband 1.165, and ver 3.0 Gekokujo grabbed from here.

After enlisting under a lord and serving for around a month under his banner, I took a leave of absence to try my luck courting a lady. After the first of my 2 weeks granted, I received a -19 hit to my honour, and suffered negative status with almost every faction after being branded a deserter! Needless to say, this sucks bigtime...

I've heard another mention of this bug appearing over on the Taleworlds board as well, but didn't bother registering an account just to post this one thing, so hopefully it does get noticed here.
