Forgive me if this question has been answered.

I started a mission quite by accident that I wasn't ready for, the first Yogi & Reggie Mission "Mouth of Madness".

Unlike any other mission, I was unable to reload from before the mission started. I tried restarting the mission, but this started the whole mission over, from the beginning. There is no option to quit. If I close the game and re-open it, I end up at the beginning of the mission. I just want to run around & kill some animals, maybe get some outposts. I am not mentally ready for this mission. Before you ask, I already put the level down to Easy. The problem is that I usually play as a bow/sniper, go the "sneak" version, and I did not maximize the correct skills prior to starting this.

Is there some way to exit the mission and reload from before you started it? the option is not in the game although it is there for campaign missions - not sure if that's a bug. I have a PS4 - is there a way to recover a previous save?
