Missing models in BIM 360 Next Gen

We are having an issue with tasks erroring out because the links models report as missing. The project has a mixture of links through desktop connector and live links to other 360 models. The 360 model links are the cause of the issue. Opening the file manually (on the desktop and task server) shows the link resolved. The automated load from clarity on a task is where it is missing. clearing the local cache from the PAC and user files is the only way we've found to resolve this. However, it keeps coming back.
