Dragon Age Inquisition Xbox

Not sure if I can make this make sense at all. There has been quite a few issues with my lastest play through, more so than normal to the point of having to close and quite the game to restart almost every 10-15mins if I'm actually lucky. It started after making it to skyhold doesn't matter which area or map I'm on, but not been able to switch between party members. If the Inquisitior goes down and it switches to the next party member and you revive her/him you can't switch back to the Inquisitior you can switch to other party members but not the Inquisitior. Other issues I have had is not been able to move on to the next part of the mission. For example at the moment I have managed to get myself to Trespass DLC (without giving up) and it's worse, going through the mirrors only to get to the point of using the mark to open the way to the next mirror only the wall didn't disappear..... Had to close the game to go back and yes it worked but having to do this every section. Then we get to the deep roads to have a section not load the NPCs  and then randomly the Inquisitior starts jumping!? I had to close the game twice with in mins for these two. There is more so much more that has been happening with this game. Is anyone else having issues? Any fixes other then closing the game and restarting?
