Sorry I wasn't clear--I thought he was talking about a bug that had been introduced since the release, but it turned out it was the other way around. The bug was present in the latest beta-1 release but fixed in git master since then.
I hope to have a beta-2 release out in the next week or so.
Anyway, that IS the version wherein I found that bug. Is that not the latest published release of the game for Windows?
