Two faction specific quests given in Helnim are missing the faction names in their description, i.e. they should have the name <Faction>: <Name> instead of <Name> to allow for easier tracking and be consistent with Vanilla. These are:
Last night I found a floating rock on Aanthrim region. Head East out of Dondril not to far [a short distance stop at the first pair of rocks on your right then turn south looking towards the small ruins on a hill]. There is a giant stone and tree here between where you are and the ruins. Just next to this tree is a small rock that is quite high up in the air you will have a job spotting it in the construction set as it is in the canopy of the tree. It needs placing on the ground or removing. Also I have seen that there are also a few up the hill to the left of the first one.
