We are starting to test our new game, Wizard's Ashes, still in its infancy but coming along---and if a tester saves the new version over the old version and tries to use an old save file, or just tries to use an old save file after deleting the old version, he gets errors from the old version coming up and problems.
The file at some point is going to be very large. To avoid testers' hair loss, can we reuse an old save file if someone wants to and not have errors (asuming new version has no errors--I don't send out a file with script errors-- but I do send it out with significant changes to old screens where someone has already been -- sometimes.
I don't mind starting over each time and I have to do it but I have one tester for whom this is a problem and he's a very good tester and a significant part of our team -- don't want to lose him. : )
Thanks for any help. Of course, if it's not possible, it's not possible.
