Moving guard towers - Endless exception loop - LAG Spam

[Sklo:D 2,210]

Moving guard towers as a GM no matter if push / pull or summon will cause an endless exception loop of nullpointerexceptions in the pollCreatures method.

 

The problem is that the Creature class for the guards left in the old place still have this.guardTower !=null after the move, but the GuardTower.class doesn't remember the guardTower before the move and causes and NPE exception when it tries to load the kingdom of it.
