As per the subject, I have a file which uses Linked blocks with Reference style layers.
If I have the layers switched off when closing and saving the file, I would assume those layers should be off when re-opening the file (just like normal layer behaviour). But they don’t. They always turn back on.
Interestingly enough the objects will remember their show/hide state on re-open. It would be great if they would also remember their layer visibility state.
