When controlling any artillery piece as 'Zeus' the ordance is not fired in the desired way.

When firing manually:
The artillery rotates, and fires normally but its height does not increase or decrease leaving it how it was when it was spawned in or affected by a player.

With the artillery computer:
The artillery fires when ordered to, and the trajectory lines show up with an estimated time, but the artillery piece does not rotate or change height and fires in the direction it was facing when out of the computer.
