The Hidden Forest

Killing the following bosses does not update the leader board:

Ssra Temple - Rhag`Zadune

ToV- Koi'Doken

ST- Nanzata

HoH- killing The Chaos does not give you a Completed flag for the zone

Is this random or always (not)happening?

Always. If you look at the leader board, no guild that has killed any of these mobs has gotten credit in almost a year.

Hehe, good catch I guess!

Fixed in next reboot.
