1) Noted down
2) Not easily ; you can try to set the draw to have 6 rounds, so it'll be on 2 weeks, though (ie: have at least 65 players)
3) It's pages for up/down, not left/right, because for left/right there are the round names shown, but nothing is shown for up/down...
4) No, it'd mess up the internal state to be at 2 different tournaments at once
5) Fixed for the next update !
6) 7) Still cannot reproduce either issue...
Also, the match shouldn't start fast forwarding. I tried and I have to manually click on "Fast Forward To Next Important Point" to start the fast forwarding on the 2nd match, so I'm not sure what's going on here...
Could you close the game the next time it happens to you, and send me your System.Log ? Maybe the engine will catch some error.
