Overwolf doens't recognise Guild Wars 2.exe
It happened to me once, got everything ok after a overworlf reinstall.
See if u dont run OW after the game is running sometimes that borks up and does not show comms in game.
Other than that make support ticket to overwolf team.
1st April joke, when gw2 receives a “balance” update.
GW2 has no support for 3rd party stuff and isn’t even a GW2 issue, this is better posted on the Overwolf or Teamspeak website.
