I have played quite a bit and haven't encountered any flaws as such... Of course there is quite large variability in distance and direction, especially in case of very uneven lies, but that's the part of the game - trying to avoid it and coping with it if necessary. I think it's WAY more realistic than the standard game, so I hope they'll put more of these...
Or perhaps some top Tour Legends are just unhappy that because of variability and bad luck they get beaten by some Legends too often?... ;)
Edit: regarding this particular bug - I read about it before (and for this reason I try to never exit the uneven lies game) and it certainly MUST be fixed. But aside from this, it's a really nice format of play...
