Every time me and my teammates open Sketch we should reconnect libraries to the files in the document setting 
In the document setting, libraries are duplicated and show loading:
Also, when someone joins the collaboration mode we should connect all libraries again
We use Sketch 99.
Hey Taha,
Thank you so much for sharing this with us! This is indeed a very unusual case and something we have not received reports of in the past.
Could you share with us more info at productsupport@sketch.com? This is something we definitely want to take a deeper look at, and provide help as soon as we can!
Thank you.
I sent email.
We followed up with @Taha via email and found that the Document could’ve been in a corrupted state, and just clearing the ~/CloudDocuments folder and re-downloading the Document from the Workspace solved the issue.
