Brother Balatin is a common spawn in Dread Lands, with a PH that shares a spawn cycle of 6 minutes. Our wiki shows him as being a 50% chance to spawn. It's widely known about this NPC that he's just a few PH killed before a repop, and is generally a very easy thing to get.

Tonight I camped his spawn for four hours, killing a PH every 6 minutes, and saw nothing but PH repops.

Prior to the recent patch, I saw him spawn after 4 PH spawns. A common spawn shouldn't be taking 4 hours to not show once. Considering the latest patch did a lot of work with variances, I believe this may have inadvertently bugged this spawn and it is no longer a common spawn.

Thanks for looking into this.
