I did another offline test of this problem on the main machine on the 6th and I get the same thing even though on the 5th with the main machine I was able to read the files offline after saving and backing up.
This happened once before on the main machine. I was running MC 6.0 beta1 on the main machine and finished the friday trading day with it closing down MC properly and backing up the data as I always do. Then Saturday I found out that beta2 was available so I installed it but when I brough up MC offline with that workspace and trying to get the friday offline data I could only see the charts up to thursdays midnight area day end. I thought this was a fluck of the upgrade so I brought up TWS and did a backfill to get the Friday data. If I remember correctly I was able view the Friday data all weekend including the next day Sunday. However that makes sense because On Sunday Yesterday is Saturday (at least no one has told me otherwise yet) and MC only dislikes yesterday so Friday data was okay.
So it seems that MC 6.0 does not like yesterday once the midnight hour has come buy. I think there must be a werewolve in this version of MC which comes out at the midnight hour

Oh God. Now I have that song "Yesterday" that the Beatles did running through my head
