One thing, correlation is not causation, and that is as indirect correlation can get.
There are FAR to many varibles for that to be the only cause, someone hops on dragonfly and the server crashes a WHOLE minute later, so many thing can happen and compound it.
Im sure if we wanted we can make a nice scatterplot of how long a server crash happens when there is at least one dragonfly play starting from the point the dragon fly joined. And you know what, that scatterplot would not look all that much different then one for vaga or stryder. The server crashes. Its unstable. What we cant have people doing is purposely crashing the server.
