Bug: Analysis stops at 100 moves

For example see http://en.lichess.org/J0Qo5rb4/. But I have a feeling someone will say it's by design...

By the way, does anyone know what "#" means, after a move number in the moves list (many from move 84, and some earlier)?

# means mate. If it says, for example, #16, it means that (with best play of both sides) you can force a mate in 16 moves.
