wow thanks for the quick reply.
Saving at -3 did stop the crashing on load thanks ...
However the reveal ore option doesn't appear to work, when you click the option the green progress bar goes half way across and just stops. (usually there is a message on the right hand side to say it's been revealed but you don't get that either) It still lets you save the file but then when you go into the game you still can't see the ore. It seems like the function doesn't complete?
Also is there an issue with copper in this release? I'm on about my 3-4 game over the last few weeks and if I find it it's in tiny QTY's, my last 2 games haven't had any I could locate whatsoever. (Hence trying to use reveal ore just to see if I can see if it's even there)
