Siege Engines And Gates

[Decarlo37]

Hello everyone
I have been playing Rome Total Realism Platinum edition and have noticed that when one of my settlements is besieged and I open the settlement and click on my garrisoned army and attack the besieging army I can't seem to get my siege engines through the gate and onto the battle field I click on the area outside the wall and they don't move they just say "orders completed" and stay in the same position. I've been searching online for anyone who might be having a similar issue and I can't find anything so I decided to write this post on here. Any help would be much appreciated.
Cheers

That's a vanilla RTW feature, siege engines are seen by the game as too big to pass through gates.
