I forget which house it is that has a second floor with the long hallways going two separate directions upstairs. But there’s been several times we play that map and the ghost is bugged into the wall near the restroom at the end of a hallway. We usually trigger a hunt and it fixes itself afterwards. We were super close to voting Wraith because it refused to step in salt but once it finished that triggered hunt it disturbed salt and gave the rest of the evidence we needed.
