OK, I know you are getting tired of me now. LOL! I just noticed that when the Crystal total goes into 7 plus digits, the Energy bolt overlays on top of the first digit in the popup menu. Not sure if I'm nitpicking or not, but I never noticed this before, either. I think I'm going to reboot this machine before I play again...I'm not sure if this stuff is my rig or the game or gremlins nipping at my graphic card.
I'd really prefer that these be logged in the bug forum, but that's my only complaint -- thanks for finding this stuff! This is fixed for 2.600. In the past, metal/crystal could never be that high, so it was never an issue until now. It's nothing to do with your rig or your graphics cards, just minor glitches in a growing game where old assumptions (such as that there would be no 7-digit costs) are not always valid anymore. Thanks again for finding stuff, it's a huge help.
