Hi,

So I have just captured the fortress and I fell down a wall and I landed between two boilers. I can't move (tried spamming the buttons) well I can move like an inch. I can't fast travel because it is a mission. When I restart mission it takes me to the same spot. I don't want to start again because I have invested hours and hours into this game and when I finally come to completing it I get stuck and it is really annoying.

Is there anything I can do or is there any way to find an earlier save? :/
