Wing/Group Buzz Crashing

[DarknessInferno]

I don't know if it's limited to Guardian sites, but we can't have more than 3 people around before it buzz crashes us all. We've been at two different sites, new and old, have cleared our caches and still the problem persists. We've also tried to stay in and out of wings, with no effect. Every single person there, shortly after a third person arrives, buzz crashes straight to dashboard.
