Sorry I didnt reply last night Nexus, I had lost my rag big time with the in game save/resume and in all honesty Id have just barraged you with abuse
Id worked my way down the highway on a warthog to a certain point and decided to go for dinner. I hit "Save and Quit".
When I came back from dinner, I hit "resume solo game"...and it put me right back inside the ops center !!
An hours game play wiped from existance; I am really chuffed off.
