This is a bit of an odd bug that appears to be more of a display error than an error that affects game play.

As shown in the first screen snapshot below, I have a mining starbase named "Valens Starbase 1" that is collecting Durantium from 3 resources.  When I double-click on the starbase I get the window shown in the second screen snapshot below that accurately shows the 3 Durantium resources that are being collected.  However, and here is the bug, if I double-click on a different starbase that only has 2 Durantium resources and then use the arrow keys to cycle through to "Valens Starbase 1", the third screen snapshot below shows that the program now only shows that it has 2 Durantium resources, not 3.  If I start on another starbase that also has 3 Durantium resources, then "Valens Starbase 1" will correctly show 3 Durantium resources.  The bug only seems to happen when I start on a starbase that has fewer resources and then cycle to a starbase that has more resources (any starbase, not just "Valens Starbase 1").

While most people would never notice this and I do not consider it to be critical, I hope your devs can find and fix this bug.
