Error loading showfiles

Hi all

I’ve been having an issue with loading show files. Programmed a show (a large one that took days :flushed:)
Saved the file and changed the name of it, the next day at the gig, the showfile wouldn’t load :open_mouth:.
Came up with “parse error” and “bad allocation”. Luckily the last autobackup file loaded and I was able to run that. It’s not the first time it’s happened, another showfile I did prior had loaded but didn’t run properly like it was corrupted.

Any thoughts on this are much appreciated
