AI stops playing

Firstly - thanks for a great project.
I've been playing on the latest version (1.3.0dev2014-11-29v10) and all goes well for a while, maybe a match or two, then I've noticed the AI (mad bot, level 10) just doesn't play any lands, which leads to simply passing the turn (slowly) and discarding. The server window shows the AI's hand, which has a bunch of land in there.
I can't copy/paste from the server log window, but there's nothing specific there, other than the odd "simulating - timed out" message. Nothing significant on the client console window either.
For reference, I'm on a mac, using java 1.7.0_71, launcher 0.3.0
Is there anything I can do to help with this one?
Dave
