Has anyone else scanned every ghost in the game and it still says Ghost Scans 5/6 at Return To Hotel Sedgwick? Earlier I played the game for the first time in a long time and noticed my scans for RTHS appeared incomplete. I did a thorough check and it appears I scanned every ghost and creature from that stage and I even have the “Back off man, I’m a scientist” achievement, so surely it’s a glitch?
You have to get a full scan on a ghost for it to count, I think. There’s probably one with only a partial scan.
I had the same problem but mine was at the museum.
I’ll try going through the level again and getting a full scan on all of the ghosts there. I’ll see if it helps, thanks for the tip 
Edit - did this earlier and now I’m at full scans. Thanks a ton, Lando
