I recall some (fairly recent) discussion of some isue whereby if you attacked with a stack the first unit attacks then the stack goes to sleep again unless expliciotly re-awakened. I also recall someone saying stacks of workers behaved similarly when given orders. I can't locate the original posts to get the details (yeh, yeh, I suck at search), and I can't reproduce any obvious problems in my test games. I have tried stacked workers giving the stack an impovement order, and all members perform it (seems right). I have also tried attacking a city with a large stack (with stack attack option not enabled) and that too behaves as expected (best unit attacks then focus returns to the rest of the stack). Can anyone clarify the issue, and what is needed to reproduce it please...?
