Disallow attacks on towns when one platform is down
Suspending play when users of Plarium Play or Facebook or mobile phones are not able to access the game but other platforms are would suspend plarium's cash flow. A less drastic measure which would make the situation a good deal more fair (and also save a lot of time and effort sorting out complaints afterwards) is to make it impossible to attack towns during such times. No one gets zeroed and a lot of stress felt by those unable to access the game but fearful that their shield is expiring is avoided.
