I second this idea! Please don't make the same mistake I made with my ill-fated C2 Feral Run - I promised the entrants they could have a copy of their Norns after the run was finished, and then my game crashed and the run had to be abandoned, and everyone lost their Norns.
So yeah, upload the Norns somewhere as a safeguard!
