I would like to know what addon causes this, I bring out a weapon in a vehicle and then put it away and my Blockhead stands up, its getting quite annoying and I still haven't figured out what addon causes it, I have tried a Fresh install in the past but no luck, everytime I try a fresh install it still happens I have also cleaned out my addons folder of known crcs(crap-ons)I have seen this happening to other players in certain servers so it must be a addon on RTB.
