No need to apologise - it's not your fault, just one of those things.
The only difference I can think of is that I'm using multiple countries (and more leagues), which I've never really done before - so potentially it's just my machine struggling with it. I guess saving / processing / and loading the list of scouting priorities are all quite high-load tasks, so maybe that's sending it over the edge.
I will give that a go though. So, sorry - do I then paste my save game file back in before I load up?
