Deck Help

I built a 12×28 deck at our permanent campground spot last year. This year the project is to put a roof over the deck, which will consist of a wood frame withbpolebarn steel over it. The problem I’m having is that over the winter about half of the vertical posts twisted, some severely, although they stayed straight otherwise. I’m left with 2 choices

1. Build off the twisted posts. I’m.being told by several people who seem to know what they are talking about that this would be fine. No one would probably ever notice and it’s just the campground. I would know though and it would bother me. Tere won’t be a whole lot of weight on it

2. Untwist the 4×4s somehow. I have a couple ideas about how to try this but I’m open to suggestions

What do you guys think about my options here?
