Wraith Hunter gone and not respawnable

Sup guys,

So I summoned the Wraith Hunter (South-East part of the map salute the memorial wall) and when he spawned in my controller disconnected and he melee'd me and naturally as with all melee touches you die. When I went back, he was NOWHERE to be found and I can not summon him again. I killed the 4 hunters you spawn at the same time so it isn't that all hunters are bugged. Anybody has an idea what to do about it? Because I need my 12 hunter masks.
