Could a dev or admin please explain how a member of another alliance ended up in one of my alliances chat groups when they were never invited in the first place? The group was just created so there is no chance they were a residual member. I would have never been aware of the issue had they not been honest and warned me. I was lucky that the uninvited guest was an ally and not enemy. This could be disastrous for all alliances and players if the groups can be insided in this manner. Please look into this matter and correct whatever the issue is.
