I was working on my design and it didn't seem to have any problem saving. When I tried opening it again it took a long time to load and "a problem occurred while trying to group shapes". This error has happened a few times before but it was always resolved after deleting some unnecessary shapes. However this time it's not working. I'm really close to finishing it so I really hope it's safe... Help?
(It might be related, that earlier I could download parts of the design and import onto another workplace with no problem, but today when I tried downloading selected parts the file was corrupt / 0 bytes)
