Hey, unfortunately this suggests your history isn’t present on your machine, as neither Cursor or SpecStory can find it. This can sometimes be cleared up by the OS, Antivirus or any “pc cleaner” software.
We don’t recommend relying on chats as stores of context or history - if you find you have lost alot of progress here, I’d recommend trying out Project Rules or consider storing any relevant codebase data within files in your project that you can @ when needed!
