Layout 2021 has been doing this since I updated.
I’ll be working in a file, save and close it, then go back later and the ‘main’ file size is 0KB. I can open the ‘backup’ ~ file, but it is always at least an hour old, usually more. I can’t very well pass this cost onto clients, so I am eating billable hours because my file is suddenly ‘empty’, and won’t open. Does anyone know why this is happening?
