Mascots stamps have functionality issues

[nhaar]

The most notable of it is, the fact that you can only get one mascot stamp per room.
Some other issues arose, for example, Rockhopper's stamp was once completely non-functional for wathever be the reason, and the same might have happened to other mascots in the past (can't be sure).
A not so worrying issue, the mascot stamps delay the response, so you get the stamp a certain amount of time after you join the room, but weirdly, if you transition a room during the time interval you don't get the stamp, the game waits the new room to load before getting the stamp. This last bit is still a bit inconclusive.
