The new Strongholds module officially launched yesterday. Cryptic has a very old-school approach to patch days, which is to say that the game never comes back up in time or actually works when it's supposed to. First they had to keep extending the scheduled maintenance, and then when the servers finally came back up, they immediately crashed again.
The game also has this weird thing going on where the launcher doesn't actually seem to do nearly as much patching as it should. Which is to say that the game told me it was fully patched up and ready to play, I logged in, and the first loading screen took ten minutes while the game was telling me that it was patching another 1100 files... better not be in a hurry to invoke!
