I've added the new items in the config but it will not limit them, anyone have any suggestions on how I can get it to work?

I'll have a look on the weekend, and see why they're not being counted.

Sorry should have came back and updated but its working fine, just added in the wrong name for entity.

Ah, that would do it. Cool, saves me a Saturday morning :P Maybe I'll stick lights on some more Helis.
