Yes, this mod has bugs. Tons of them. Some of them quest breaking or even game breaking. But it's competely free and the devs are working on fixing glitches all the time. Just join the Dischord server to report problems, and the team addresses them almost immediately. In a year's time, this will be the best Fallout game ever released by the modding community. If you hate bugs, just wait until then. It will still be free.
