Hm interesting. Well, I found this older bug report handled by kanras.

This has some discussion about how it is not necessary to kill both Vorash and Deep. So, I'm not changing that part until further evidence is provided.
Pending update,
Deep and Vorash will depop after 80 minutes as long they aren't engaged.
