Minor patch pushed today. So, it turns out that I forgot to update the version number for the last one - which means if you had been playing on unstable it might have allowed you to try loading incompatible saves. Now I can't change it without making it reject any saves you might have created in the last week. So. Oops? Anyway, it's marked as compatible with the previous version so you won't lose your saves, but saves older than last week's update will not work. Also fixed - or, more accurately, patched over - a couple of crash bug that came through the automatic reporting. Only one of them made sense. The rest should have been impossible situations but - well, someone encountered them. Now they might lead to oddities in game but they shouldn't crash outright.
