Icon of sin not working.

Here is the map in question, I am making a map like hr2final.wad map30 and the icon of sin will not work, It is not set as deaf, but it will not wake up when I enter the final room. This map is for MAP30.

I just need some help on getting it to work.

#EDIT

I have uploaded the modified version, and the spawners stil will not react. I am using Zdoom 2.3.1 on Linux and the Afrits will see me but the spawners will not react to me, I had a look at the scythe 2 dehacked file and that is nto the cause, I wonder what the cause is...

The monster spawners are facing the wrong way, they have to "see" you just like a normal monster would right now, a line blocks the vision of the spawners. They are also facing the wrong way.

They are still facing the wrong way. If you walk around to the back of the room, they will see you
