>>Whats been added that interferes with the spell these days?

The main addition in recent years would be Grimswarm warcamps. You'll generally have to wait for the body to be, uh, worked on a bit more, and then kicked out into a regular room. I think that takes two or three minutes?

They may also be inside what I call special places that are blocked. Some temples, secret rooms, sometimes a gm has people where there not able to be found. I think you get that result if someone is using unpresence also.
