Dust Palace

So here was me playing a strike on Dust Palace the other night and we were down the the last Psion (I think I've spelled that correctly) and we were getting hammered every direction. I had one last round in my legendary rocket launcher and being a hunter I decided to go invisible and try and get the bastard. Well it was a 1 in a million snap shot but I hit the Psion square in the face with said rocket launcher, but what was funny was watching the Psion pirouette into the sky at 100kmh and disappear into the distance. Strike done! I know this was a bug in VoG but it also appears to be in Dust Palace. Anyone else experienced this? Cheers, Alan
