We tried everything but can`t reproduce. It would help if you would have a town where we can reproduce it.
Would just need to know your account name, town name, and which army to enter siege of what town with. You might want to place army we need to use over the NPC town where your getting that - and I guess add new siege weapons, at least a few to that army.
And your town/army won`t be changed in any way, we`ll just make a copy of it for our office server
