Double messages on EU
On the EU server whenever someone sends you a message, it shows up 2 times. This doesn't occur on the US server. I think it has to do with the new message ding, it might have screwed something up.
Here is a picture to make you understand better:

The issue you linked @TiTo-418 I think is the bug were sometimes messages are recieved several times, can be more than 2 times.
This issue seems to only happen on EU, and it's always two messages you recieve.
Just tested, seems to work fine http://prntscr.com/8u81x9
Well it happens to @MobbareKurtZ so gonna keep this open.
