[Update: The Croteam member who confirmed the issue has said that the studio may be able to fix everything. A new patch will arrive tomorrow that will attempt to rescue both old and new saves. Fingers crossed!]
A small update for Serious Sam 3: BFE went out today and some users were in for a rather nasty surprise -- myself included. The update, which was intended to make minor fixes, has also made a number of saved games unobtainable. Considering some of these levels take an hour to do, that's seriously bad news.
"Oh, shoots! This was certainly not expected, but now that you say, I know what caused it," said a Croteam member on Steam. "The update wasn't supposed to be that big. It broke saves on levels #1, #2, #9 and #12 because those were accidentally included in the update.
"Will ship another one tomorrow, and we can revert this problem by restoring old versions of the levels. Unfortunately, if we do that, then the revert will break saves on those created today. Not sure which poison to take now."
So, the current situation is that Croteam does not know if it is willing to risk a fix. Unfortunately, Level 12 is stupidly long (Dtoid reader LordGremlin logged over three hours). I don't know how long I sunk into it, but I wasn't done with that single stage after two sessions and I wanted to get the game cleared today so the review could go up tomorrow. That's not happening now, obviously.
Considering Level 12 manages to suck a lot of the fun out of the game right at the very end by being so lengthy and dreary, I can't think of a worse thing to force gamers to replay. Man, I'm pissed.
