Several problems; the configuration parser is failing to find an element in the spawn configuration and you have unresolved variables (variables that are not declared).

Can you please paste the code on line 3494 (and a hundred or so lines preceding it) in the combat assistant class so I can help you fix it.

Code:

		if(usingBow && usingCross && c.usingMagic && usingOtherRangeWeapons) {
					c.getPA().followPlayer();
					c.stopMovement();
		} else {
					c.followId = 0;
					c.followId2 = i;
		}

Heres my whole combatassisant.java

The problem is those two variables are only declared under attacknpc and attackplayer.
