NPC Spawn Issue: Pained soul in Trakanons Teeth

[Gugmo ravesalot]

This mob spawn rate seems to be ridiculously low, im pretty convinced after spending most of the weekend camping this and through talking to other people that have done this camp, that the rate is bugged.

Other people ive talked to so far its take them 18,22,32 hours to get him to spawn and know of one person whos spent 52 hours in total at the camp no spawn, no joke.

I've spent more than 22 hours at the camp without seeing him, Can this spawn be comfirmed to be working or broken please ?
