100%, like I already said I think it's also realistic to expect some resources to simply have been depleted in time so of course we wouldn't have all the records, etc.

THAT BEING SAID... Do you mind if then I return to my original northern Italian claim? Moving to Sardinia was exactly because of 'ugh, I don't want to bother searching for everything so I'll just go with something that has a good cross section of historical resources' so if possible I'd go with my original idea.

You can go back to your original location, but I will say this will be the last time you can swap.
