Graham, could there have been a mistake with Ember? I’ve been following the tournament, and for some reason, it’s making some really stupid blunders there; yet, when I run the same position on my own computer using the same version of Ember, there isn't even a hint of that bad move. For example, the game against Pawnstar ended in a draw, but in the position `3r2k1/5p2/pq2p1p1/1p6/1P1b2P1/P4PP1/3Q2K1/R2R4 b - - 5 33`, Ember 1.1.1 played `a5`.
However, when running it on my machine, it doesn't even consider that move and immediately selects the best one.
Could the wrong version have been downloaded? Or is it some other kind of error?

If an error occurred, I would like the engine replaced and its previous results reset.
