Quite a few Almas Thirr interiors have northmarkers errors, I have decided to compile a list here to not clog the bugtracker too much. The ones I have found (besides the ones I reported seperately already) are:

Almas Thirr, Guild of Mages
Almas Thirr, Hetman Llothro's house
Almas Thirr, Anomoleth: Outfitter
Almas Thirr, Dockyard Warehouse
Almas Thirr, Revis Arano's House
Almas Thirr, Ralyn Velor's House
Almas Thirr, Danse Orani's House
Almas Thirr, Prison
