Some players reported an issue that caused conflicts with the quest menu and hero's when saving and loading the game. Something we missed on our end. This has now been fixed. You should be able to save and load as many times as you like without errors.
Remember to opt-in to the Public_Beta build to get a first look at the new Groggery and Economy System that we're now working on when it's available.
Thanks Again,
