I am totally stuck in the quest in Vault 22. I am being told I have to go to a room named something with "Pest test" level or something and I can see it in my map in the "food" level but I can't get there. In one of the rooms in the "food" level I can see a cave and in the room there are some broken computers. It is saying I am standing in the entrance to the "Pest test" level. Where is it?
