Heads up for those who haven’t experienced this yet. I ventured out to the prison to do a Marcus Mop Up mission and I cannot enter the prison. The outcropping that you launch to now has a grouping of boulders blocking the way as well as an invisible wall thus keeping me from grenade jumping.
I have only jumped over the fence a scant few times. I generally hit the wall and walk around. Not anymore apparently. I got frustrated trying to get in and eventually gave up.
Making you jump the gap and over the wall in one go was an odd update. Perplexing really.
