possible bug with Horseback adventure?

I am doing the horseback adventure. Using Sid V's guide I attacked camp #16 (leader camp for section). I blocked camp #14 seconds before the attack. I watched the battle begin at camp #16. Normally the progress bar shows up shortly but it never did. It was in that begining fight mode for over 10 min with no progress bar(just dust flying around the camp). When the fight finally ended all camps were cleared as it should be because i attached the leader camp. However in checking my battle report, it shows i attacked camp #15! That is impossible as the section would not have cleared.

I am 100% positive i attacked camp #16. Could a possible bug have caused this.

any feedback on this is appreciated!

I just experienced something similar on this adventure. I cleared one leader camp and one camp disappeared off the map. Now I've attacked all the camps, no more visible on the map, but the adventure is not completing. My garrisons are all that's left and waiting orders, but no enemy camps to attack. 18 hours left in the adventure. I will submit a bug report to tech support and see what they find out.
