I've had corrupted games too. Halfway through a game (40 or so letters left) they played EEK, I played a W to make it WEEK, and then when I got the board back the EK were gone, it showed that they had played WE where WEEK used to be, and it said that I had lost the game. My letters were all different too.
Clearing the data and cache and logging in again fixed the problem, and returned the game to where it had been (with WEEK on the board and it being the other person's turn).
Works just fine on my rooted DInc and OK on my rooted NOOKcolor. The only problem on the NC is that the letter blocks at the bottom are kinda hidden a little bit--not always able to see the full letter and differentiate between I or L, B or R, etc.
All of my Droid friends have been forced to play with me...and they love it. One of them, when I brought it up, said she looked for it before cuz she played it on her iPad. Told her it came out yesterday, so all is well.
This Network error that is only resolved by reinstalling is a bit annoying though.
