Coop custom end level room not working
So I opened up the end level room instance too see if I was missing anything in it. I noticed a few logic_relays laying around, as well as some sounds, some env_fades and a coop_manager. I also noticed that the instance for the disassemblers in there had a Fix Up name of "orange" and "blue". So I copied all of the entities into my end level room, and changed the fix up name of my two disassemblers into orange and blue. Tried the map out again and...still nothing. Exact same thing as before.
I looked up and down the wiki and these boards to see if anyone had a similar problem or knew what to do, and there was no luck there.
I was wondering if anyone knew what I was doing wrong? If not, then maybe I should just make a copy of the other instance and edit that to what I want it to look like 
Any ideas?
