It has been my understanding that when the icon for a troop greys out, that means all of them have died. Today I had a juggernaut still fighting after the icon was greyed out. Photo attached. https://www.dropbox.com/s/0bbslt2hrtczvmx/2015-03-20 15.00.55.png
Thanks for highlighting this, we're taking a look at it now. It appears to have come about with the introduction of the troop donation. Fear not, it will be investigated and fixed for the next update.
Yes thanks, don't worry we're aware of how to recreate the problem. We're just looking into what code change has caused it.
Great to see a civil, productive and positive thread (big tick for both Hong Kong Hunter's approach on this bug and Chris's timely response).... I also support Kelani's stand on all this (as referred to in other threads). Keep up the great attitude..
