Great news everyone!,
First off, I'd like to thank everyone who's been supportive and helpful in this matter. You've been very patient and I wouldn't have done this without your help. I would also like to give a big thank you to Xander for being the one to put the finger right on the problem, he was literally (in a figurative way) poking the problem.
The save problem was caused by the notice board and whenever a player would accept a quest from the notice board, any attempts at saving the game would be 100% corrupted.
I've corrected the problem and taking quests from the notice board will no longer corrupt save files!
So save away without fear!
Disclaimer:
The game currently saves the state of the game, so when we add new features and the like or delete them, the old save will not update since it only saved that instance of the game, it would only update if we made changes to existing features. We'll be working on a long term solution to this problem in the coming patches, but it will take some time, since we want to bring out as much content as possible at the sametime.
So for now, please read the Corrupt Save File Sticky in the forums, if you haven't
Thank you,
Stoneworks Games
