Guard Kristrum in Thurg

[Cyrano]

She's patching about 5 feet back and forth at ent to bridge and periodically falls through the ice a little. I believe she should path a long way, back through the gates, and into a guard tower if I remember correctly. Either way her path is too small.

[Brut]

NPCs in general struggle to reach that spot, if you aggro mobs in the city and just run to the ice bridge, they run back and forth at the arcway forever.
