Hi Bill. I just wanted to say thank you for all of this information...it's great! I've been searching and trying to find an answer to something without bugging you I think I need your help.
Is there a way I can tell, without actually having to click on an individual unit, which ones are available for an upgrade? I'm asking because I have clicked on units with supply of 9, haven't been moved, I have already researched the technology needed, yet the word upgrade is still faded. Some requirement doesn't seem to have met and not sure what it is? Oh, I have had plenty of MPP to purchase the upgrade. Thanks Bill!
