Runes in Grahtwood: limited spawn points or lootbot lockdown?

Paradoxia

I'd been questing in Grahtwood for a few hours this morning trying to finish up Cadwell's crap when it occured to me that I had not seen a single runestone node. I have 3/3 in Keen Eye and I had been all over the zone. There were the usual sadsack VR16s doing rounds but they usually stick to the edge and buildings.

Hopefully this isn't the norm for Cadwell's Auridon. Unlike the farmbots, I actually need the stones to level Enchanting.

I personally found that Grathwood was the easiest zone to farm rune stones
