So, i tested this new version.. and deleted it immediately and
went back to the good old working (naris) version 2.x
In this version, the anti soundspam "duration" seems not to work anymore
terrible!
players could play dozen of sounds together...
Also, the clientprefs don't save the status on map change while you are online in the server.
If you are not in the server, and the map has changed, you connect then again, the last status of !sounds is saved correctly.
