We are a company specialized in architectural visualization and have been working with Blender since 2015.
These days one of my employees had several times the same problem. A deactivated collection was deleted when closing and reopening the file. We are working on version 2.93.4.
It’s not practical, because if you’re not careful, you don’t realise that part of the project is missing.
Does anyone have any ideas? I’m not sure where to look? Is there perhaps a shortcut or a function that has been activated unintentionally?
Thank you in advance for your help.
Good day and best regards,
