Very nice mod, and they made female githyankis look a lot nicer.
Not sure...this is what I found:
Can mods deactivate achievements? No, it should not affect your achievements. This isn't console where game devs can stop you from getting your achievemnets if you made changes to your game. Some games do disable achievements when mods are involved, like Skyrim. Ironically enough, there is a mod that re-enabled achievements.
