There's your problem.
Change the Colon's Event Number to, say, 200 (and change the ANP to 0200:0010:0000 or 0200:0010:0002) and try again.
So the H/V Trigger is supposed to be Event #0091 and have an I.D of #112 wheras the Colon's Event is supposed to be different, right?
I'm also considering looking into the original CS Script (i.e Map 29: Sand Zone Residence, so I'll post it if you want.
