I am really disappointed in KIXEYE's programing.
When I was completing my final and last wave (30) I have to say that I actually won the wave!
For some unknown reason the game stuck with gattling trucks shooting at something that wasn't there.
The only way to get out of it was to restart FB War Commander to take it out of being frozen (which I did) OR click on "surrender" which I was NOT going to do .....
Event though this is a "FREE" game, after all the hassles with the recent patches and updates, I must say I'm pretty disappointed and frustrated with the recent develpoment of War Commander ...
That's it for me with this challenge or any future challenges .... totally screwed up ..
