When will this patch be available to download for the GoG version?
As of today, they're now on patch 1.5.4. And it's a big one. So the GOG version is now two beta patches behind.
Edit: OOPS! I spoke too soon. I checked for an update, which wasn't there. Then posted my initial response. Then as soon as the window closed, an update showed up for M&B 2. COOL!
Edit 2: Looks like it's version 1.5.3, not 1.5.4. At least it's a little bit of the new stuff.
