I tested this against the AI, and here is a screenshot showing my units not attacking:
Although this is just against the AI, I am fairly sure this is still the case against human players, although I haven't been able to test for sure if this is the case or not.
It seems to me like a bug, but I'm sure that loads of people would have noticed it if that were the case. Could there be something wrong at my end, and if so, then what? I've tried a clean reinstall but that hasn't changed anything. Any help would be much appreciated.
