some bugs:
1. if you Place a certain amount of units (100 i Think) everyone walk past eachother, ignoring the enemy and keep Walking.
2. if you Place anything under a Tower and start the battle then go back to custom battle its on the Tower, i dont know if this is supposed to be because its my way to get ballista on to the Towers. if you remove this then please make it so that you can Place ballista on a Tower.3. if you Place 20 catapult or ballista in a row they fly up into the skies, but glitch number 2 fixes this because if you Place them in the sky then start the battle and then go back into the custom battle they are on the ground again.
:P
