Hi!
Last 2-3 days or so I`ve had many many crashes that lead to GW client asking to repair game data, after a long repair a new crash may still happen in minutes:now I only just noticed it seems to come when I open the map and zoom out on the map. Also happened few times after someone pinged WP & I clicked it to see, not sure if I zoomed then.
Not sure if this is the only way it happens, but avoiding zooming on map just kept me many hours in game, then did it once and instant crash .
I let the client send couple of reports to Anet, but tought I´d mention it here too
