No, please don’t erase your save, it should migrate automatically. In v0.4.0, open the Career screen from the main menu or between nights. The challenges are listed there, and the travel buttons unlock once you’ve reached the fourth lighthouse.
If you don’t see the Career button at all, the browser is probably still running the previous build. Closing the game and reopening it, or doing a hard refresh with Ctrl+F5, should fix it without deleting your save. Let me know if the Career screen is there but still doesn’t show the challenges, then it’s a bug and I’ll investigate it.
