Update if anyone's interested...Raised a ticket, and as I'd kept fairly decent notes was able to get a nice credits compensation - but (and this is the annoying bit) it didn't apply to the exploring credits. So basically, pretty worthless (well, to me, as I'm after the Elite status, not credits).
So, in a nutshell, ended up with credits, but 18K (or 18 hours, roughly) away from where I was, and no exploration XP...which means facing at least another couple of months (not on holiday any more, unfortunately) just to get back to where I was. Honestly don't think I can take that (and even if I did something else, the thought of still having all this ahead of me is just too much!). So I'm out of here for a bit - nice game, but not too well designed or thought out in parts. (At least in the old days if my tape got mangled, I could hack a new save!!! ;-) )
