It seems you forgot to mark ver. 2.40's compatibility upon upload to Itch. This will prevent the Itch App from allowing existing owners to update to this current version. Please fix.

Compatibility with saves from earlier versions of Bad Manners is not guaranteed. If you wish to try using existing saves, we recommend using saves from a previous version of the game that were created in the morning at the office location after all events have been completed. A save created at this time is more likely to be compatible with later versions of the game. However, we strongly recommend starting a new game and selecting a chapter you haven’t played yet from the menu, rather than using existing saves.
