I started a new thread Wednesay night, when 5.1 launched. Today, I've been working extensively on this thread, uploading files and photos. I'm experiencing Chat telling me things that we have together proved false or incorrect, contradicting decisions we have previously made based on data. I've corrected it at least 6 times today. When I've expressed frustration, it tells me that the files and photos that uploaded just hours ago, on this thread, have expired, so it no longer has access to that data. This is concerning. Anyone else having issues?
