thief shortbow geting invaled target

i have found out why we keep geting this invaled target when we use sb5. this happens becouse when you try to blink to a location the curser will sometimes go up to nothing or under the map make the target location invaled for the blink. i was testing this in wvw when i found out how it was brocken. now that i know what the issue is for invaled target now anet just needs to fix this.
