Control group / resource generator bug
Rather serious bug I almost forgot to mention. I believe it was in this game, Ga522b3f3afb84fe0beb1677a00cc5762.
I have the resource generator building/tab assigned to 4 as my standard hotkey (so 4 is not a control group for me). At one point in the game I accidentally tried to assign a unit(s) to 4 using ctrl-4. Following that, 4 failed to work properly by selecting the resources building/tab, but furthermore I couldn't even select the resources tab by clicking for the rest of the game. This left me unable to control my generator at all. Fortunately I discovered that the automatic generator production seems to have improved since I last tried it - for instance, when I was short on Energy it automatically built Energy multiple times in a row. Nonetheless, this is a pretty serious problem - not only did it mess up my hotkey, but it actually messed up the clickable button somehow as well.
Good catch! thanks.
Thanks for finding this and the detailed report! I'll work on a fix for this.
