u need to keep the weap u picked as dummy along with the skill on, i tried to put 3 forcepack weapons on and it always got me HTD after a minute or two of gameplay. if you keep the weap and skill u had on when u pressed dummy it should stop you from getting HTD. the only reason i was able to have on 3 fp weaps before was due to the idm but since it hasnt been updated yet you should stick to 2 weaps
