Dhirim siege tower missing!

[Rodolph]

hello guys.
I´m helping Lady Isolla to take Swadia, and my last target is Dhirim, but when i build the siege tower and i choose to lead my soldiers in the assault the tower dissapears and we look like a bunch of idiots trying to punch the walls while the crossbowmen pee on us.
I don´t want to send my soldiers alone since, they always get their sorry asses kicked.
What can i do?

Thanks.

P.S.
There is another post talking about this, but the fact is that there is a siege tower, but when i get near it dissapears, so i build it but it suddenly goes hell.

The tower is actually FLYING in the sky (look up!)

Thanks for the fix!!!
