[BUG] Demigods getting stuck when a fort appears

As title says, when the war rank increases from 4-5 or 5-6 forts will appear on the map near your base.

I had a rook standing near the fort spawn point and when it spawned, i had a about 1/3rd of my rook avatar in the fort, making him stuck.

I was stuck for for quite some time and had to more or less suck out the HP of the fort (thus destroying it) using the rook ability to free myself.
