Must is a pretty strong word. Why?
Thunderbird starts to download all the messages as if they hadn't been never downloaded.

I suspect something like CCleaner is deleting your popstate.dat file https://stackoverflow.com/questions/318673/where-does-thunderbird-store-the-uid-of-the-last-message-downloaded-via-pop file
