Multiplayer Delve - Guests cannot leave mines until host leaves the entire instance

Guests cannot touch the crawler to exit the mines. They can only exit when the host dies or leaves the instance. This spawns a portal for them to exit, there is no other way to exit the mines as a guest.

Additionally, guests DC to login when attempting to use the Delve portal in the host's hideout to go to the host's mine encampment.
