Reinstall the game.

Maybe you have a problem in your computer. You seems to be the only one with that kind of problem with the the game.

Can you post your current configuration ?

King on blue team can go to an unreachable position below tower as show on the screen.

I don't know if they managed to get there by falling from the tower or climbing rocks ?

They seems to also be able to hide in their spawn, near boats, where you can't reach them.

They can then run away far away outside of the castle on the left side of the map and cannot be killed.
