Not sure if this is already reported, but here it goes.
I was playing a FvA game, id=232747.
I muted the other guy (sorry whaskell, it was unintentional). The messages from whaskell disappear as expected. If i unmute the guy his messages appear again, and again that is the expected behaviour. But now, if i refresh the page on the Board button, the guy is mutted again.
Even though the game is already finished i can still see this happening.
In short:
Mute a player

Unmute a player

Refresh the board - the player is muted again.
