Castle Crashers, a side-scrolling game developed by The Behemoth, shall be getting a update that should fix the lost saved data bug, as well as multiplayer connection problems.

Even though the dev doesn't know when the update will be released, here is a suggestion which may help you retrieve your lost data.

We don’t have a specific time frame yet but we have been working on all known issues as soon as they appeared. Our team has gone without rum and biscuits since we became aware of the issues and will continue to deprive our programming team of both sleep and contact with family and friends (they don’t really have friends).
