The problem is that when you remove this actor from the world in the vermoordMonster method, then go back to the act method, it then calls the vermoordNachtbaas method, which require the actor still be in the world. Easy fix is to either change line 11 (in act) to:
?
1
if (getWorld() != null) vermoordNachtbaas();
OR, insert the following line between lines 10 and 11 (in act):
?
1
if (getWorld() == null) return;
