Guild Wars 2

happend to me 2 times during a match when hitting my F3 and F4 skills the slick shoes and elixor gun tools my game instantally crashes no crash reports the game practally ALT f4.

still experenceing crashes in relation to scrapper and the F4 skill (super speed) my F4 skill is maped to Left ALT key. and im able to reproduce bug serveral times. but there is no crash report due the the game completally closing out.
