Game Breaking! CVRIE freezed, DogMeat stuck infront of Fort Hagen and Nick Valentine totally ignore me! (And relationship prob. with Preston)

[Nghiapro]

Plz read: I must warn you that my English suck since I've just moved to the the U.S for 2 months and started learning English 4 months ago, and this probably have never appear anywhere else on the Internet! I hope that this topic remain here even after it's solved for other people like me! I'm the type of gamer who will not keep old save games and delete them after 5 saves and type like a machine interface.

I got 3 main problems! And 1 minnor but hurt my brain!
1. Curie (or CVRIE as some people prefer) - With new synth body for detail, completely "pause" in 1 spot, she fast travel with me but will not move, take order by will not do it and talking to me with her back!
2. Nick Valentine totally ignore me except talking about Diamond City people while in the same room next to him, his Secretary - Ellie Perkin constantly warn me to be careful in Vault where Nick's trapped, and I think it's because of the game's limitations! I'll fill you in next part!
3. DogMeat keep sitting infront of the barricaded door of Fort Hagen (sound familiar?) after I done the quest Reunion unless I sent him home.
4. (This is the minnor one) Preston Garvey IS IN LOVE WITH ME!!!!!!!!!!!!!!!! AND I'M NOT GAYYYYY!!!!!!!!!!!!!!!!!!!!!!!!!

Some reason led to these:
1. Don't really know! Just suddenly like that! And it also appear happened to other people with different companions!

2. n 3. When I first start the game, at level 5, I managed to explore Fort Hagen without knowing that it's invole in the Reunion Quest so the "Human's Stupidity and Curiosity" force me to explore the Fort without the help of Nick or DogMeat (and so do all the buildings I encounter on the way which gave me lot of Stim and RadAway). Just like some of the Hardcore gamers out there I also managed to chop Kellogg's head off while in critical state and escaped his remaining synths (The BOS shown up). The quest (which appear after I reach certain point inside the Fort) said "Search for more Clues" but I ignore it because I was trying to save my sorry ass for getting in there. Then I fought my way to Diamond City, done all the stuff to grant access to the "City", go to Nick's Office, receive the quest to rescue him (I'm level 20 by then). But again, forgot to make the interview with Piper, go back to Fort Hagen and took care of the remain synths, search his terminal, head back to rescue the "Synth detective" but now the marker point inside Diamond City which confused me. I found him and Piper inside his office and he said: "You're back, what happened to your son?" like he know me before. Talked to him and Piper, he heading out alone. After that I was suppose to head to Memory Den in Good Neighbor, but the Unlikely Nick Valentine quest mark still on his head and I spoke to him, now he ask: "... Why do you come all this way, risk life and limbs, for an old Private Eye?" IN MIDDLE OF DC MARKET!!!!! I then do the interview with Piper, go to Memory Den, finish the quest and now he staying in his office with her secretary talking about " Crap-I-Don't-Care " while his secretary keep warn me about the Vault. When I recruit DogMeat he headed straight to the main door of Fort Hagen and sit there until I sent him home, DogMeat will not fast travel with me, taking and do my command but after that he back to his "position"!

4. When Preston talk to me at the highest affinity point where the "Romance" option appears, my sister pissed me off by clicking on it and I'm not GAY! Now he keep calling me babe and bang me whenever I sleep near him (The Castle for Example)!

Solutions and Fixes I tried for my self:
1. Recycle actor command on CVRIE, it seem to fix the problem but brought an even bigger problem! I cannot max out affinity with her since the code recycle her to before her personal quest and act like Miss Nanny variant! There's no way to reset her personal quest again and the posibilities this bug will happen again is as high as 98,735% on the same companion which is her!
2. Tried to recycle Nick either, won't work, he still staying in his office talking crap ( with the different is now he's naked with the body of a Gen 2 synth ), set stages and complete the quest by command like many people suggestion but no use. I did save before try anything on him but, heh, lucky me, the save broken for some reason T_T!
3. Don't know what to do with this since all the answer I dug up from other sites give me either no go solution or random answer for random stuff that don't even any where near the topic and stop there!
4. Recycle actor won't work on Preston and the CA_affinity of him still higher than 1000 and unable to reverse (Luckily this time the save is function). I left him at the castle so it'll "cool off"... but heck no! I left him since level 31 and when I went back to fight the Institute at level 159, he still "Violating My Body Without My Permit"!

I suggest that any one who interest in these problem share this to whoever playing Fallout 4 on PC out there so there'll be more solutions to this! Because I DOUBT that this will be solve soon and P.A.M calculated the chanced are 13.555555...% this will be solve within a year unless Bethesda is in this and that chance is even lower as 0.159%
