I haven't seen them. So basically you state the duping is possible, without being able to prove it. Good job.
I am concerned about the state of the server as well, but it's pointless but complain about error that cannot be proven. And I say this because I'm a SW engineer, and if a tester comes to me that there is a bug in the SW but they can't prove it with a log file or some sort of proof, I'm gonna tell them to fuck off, stop wasting my time.
