Multiple states toggle wrong state

[Mooselk]

Describe the bug
Toggling state with 2+ active states toggles wrong state. Might be toggling first state in the collection.

NPCLib JAR name
npclib-plugin-2.11-SNAPSHOT.jar

To Reproduce
Steps to reproduce the behavior:

// toggle 2 states
npc.toggleState(NPCState.ON_FIRE);
npc.toggleState(NPCState.CROUCHED);

// toggles crouch instead of fire
npc.toggleState(NPCState.ON_FIRE);

Expected behavior
Toggle state fire should toggle state fire instead of crouched and vice versa.
