It seems collaborate has stopped working first I updated my project to 2018 from 5.6. Before I pushed, it all worked fine. when I transferred via collaborate, the project to my osx machine, it all downloaded but some of the prefabs lost their references. So i thought I would do a fresh download from collaborate, and then this started happening. I am unable to list the first error because it only comes up after attempting to download a whole project which takes about an hour. But i was curious so I logged into the web portal and looked at the assets of the project and then I get this errors Unable to retrieve ignored paths (-1) the worst part is that It not just that project. I want to other projects and gave the same error, which has me pretty worried. I'm really hoping something hasn't gone seriously wrong on the unity servers.
