If your on PC use console commands, if your on console try loading a previous save were you knew Lydia wasn't glitched, if you load the save file and she is still glitched try shutting down your console, if none of these things work then try asking this on GameFaqs 

[QUOTE="michaelP4"]We're very quick to focus on the negative. Here's the positive: we managed to get GS to rethink its position regarding unions. That's quite significant. One thing that is certain is the unions feature itself will be gone. However, the communities - the most important part - will be preserved in some shape or form. Sure, you may not be able to control the board anymore, but honestly, the only powers you had were closing and sticking topics. How often did you do that? And yes, you can and should rely on mods to help you out - that's what we're here for. So don't be afraid to ask one of us to stick or close a topic. Chances are, one of us may even be a regular at your board, and will help keep it clean. As for positions within the communities: you can still have an informal organisation. Create a topic detailing who is what and does what - that should provide recognition. The leader and officer positions in reality only gave you a tag and the power to close/stick topics - they weren't that great really and were all for show. You can still achieve that same effect of organisation. At the end of the day, we have been victorious here. We got GS to rethink what its doing. Instead of no unions, we've got a guarantee that they will be continued as regular boards (which is really what unions are for the most part). GS aren't obligate to do that and have been quite generous to us for doing that. You no longer have to move off site to continue your communities - which is a lot harder than it sounds. How will you get new recruits? What will be the ToU? Who will keep the leader and officers in check - can you trust them with a huge amount of control and power? What about other features - GS will have an entire site load of features - will you be able to keep up? Moving off site sounds attractive at first, but when you get into the details, it's actually harder than you'd think. GS has taken care of the stuff I've listed and more. You will miss its supporting structure if you were to go off site. With what we have achieved, I don't think any community needs to leave GS now - but of course, it's entirely up to them.Juniorpower

Yeah, it's not like we're all starting from scratch or anything. Friend lists, game lists, etc. will all be migrated over.LarkAnderson

If memory serves, I believe he said that it'll be open to all users. No more union leaders or officers.F22_King_Raptor
