<usage name="Lunapark"/>
is not assigned to anything in the mapgroupproto.xml. However some items use it in the types.xml. And of course it would be good for server owners, to have specific loot configured for the lunaparks.
In the mapgroupproto the lunapark assets use this flags:
<usage name="Town" />
<usage name="Village" />
<usage name="Hunting" />

Why is it this way?
