I am on the neon arterial part of the campaign, and just finished fighting my way through a whole bunch of COV cultitsts who were all on level then I go down to the vault and encounter a wraith that is lvl 26. Whats up with that?
The main reason this could happen would be higher level players in Co-op other than that . Im not quite sure why this would happen.
Possibly not completing enough side quests .
