Hi fly

then realised I had not done what was advised ie to save game before starting campaign in bunker

A manual save must be made before starting the patrol.

I then tried starting from an earlier save which worked but after saving that game would not load again

You still have not made the bunker save before starting the patrol.
I usually request the mission and then do the save.
Any game play setting changes should be done before the bunker save.

Any previous save you load will make no difference without the bunker save, you would need to go back to the original automatic 1st save in base and start again.
