Indeed, I missed that note about gender changing not being available. As far as I'm aware the only problems caused by the MarriageAndMore mod are reverting some GUI that would add new features for v1.9a and causing crashes when clicking on the combat party members while exploring.
The only times when it's causing a crash for you is when you try heal them for example and click on the "?" mark on them by mistake. Thats what i got so far about the crash.
I was able to make the Arcis version of the mod work, but unfortunately like you said the Gender change option was removed and it doesn't look like they've been able to make a version of it that's compatible with it.
It's not that he couldnt make it work. It's more like he's either not playing this game anymore, dont have the time for it or just lazy to update it. My best quess it's that he dosn't playing this game anymore.
