When selecting a creep on the UI in screeps.com, the right-hand sidebar shows the amount of resource that the creep is carrying.

However, a recent bug has been introduced where this number does not update in real-time.  Instead, you have to select another creep / structure, and then return to the original creep to get the number to update.

This number used to change in real-time.

A neighbor of mine suddenly disappeared from room E49S35, so I went to check out the room's history.  However, for all recent ticks, I just get NO DATA. The last tick where history is showing seems to be 13583019.  I make this out to be maybe nine to ten hours ago (current game time is 13595889).
