Ballistas!!!!

[Rabblerouser]

Attacking smaller, player controlled cities, and my ballista switches target to City Hall, AFTER I send the attack, regardlesa of what I set them to attack. Do they only attack targets over a certain building level? This is so frustrating.

Does this happened multiple times?

I only saw restrictions to target existing buildings >zero level. Maybe your opponent has his building been destructed during your ballistas walk time?

Are you on Android? I noticed it is a bug. You should check your reports tho. Although after you launch it shows target as City Hall, when they actually hit your target, it does strike what you originally requested. It looks wrong, but it will work as it should, it just doesn't show correctly while en-route. Like I said, double check your reports.
