A similar thing happend to me a few years ago, I rolled out of the vh at V base and the ack killed a buff. I being the closest I suppose was awarded the proxy, but instead of getting 1 2 or 3 I got 254 in the matter of under a minute. I dont beleive I got any perk points for this, however I never hit the buffs, I dont know if bush landed hits or not or if it would make a differnce.
