Why are all progress of daily, weekly and mod reward lost on host migration?

[Guest]

There are so many host migrations happening in Conclave, and all progress is lost. 

Why is this even a thing? Yet, all experience earned in the match is kept.

Host migration immediately flags the game as a private match. The only one not effected by this strangely appears to be the new host. You cannot gain rep or challenge progress, and it often invalidates the existing progress. 

So the rule of thumb when trying to do things in conclave is, when host migrates, abandon ship.

The game does, however, feel perfectly free to consume the challenges you've already completed in that match, just not give you credit for them on the weekly ones.

I suspect there is a challenge complete flag that saves regardless, and with private match taking over, consumes the challenge as "done" without rewarding you.
