Public release of 2.0. No cheats used. Only modification made is Krag's armour fix.
Freefolk party had a few wights and a wight giant in it. Sadly, I couldn't screenshot it in a heat of battle. They must've recruited them from prisoners, as I've seen some wight giants in the dungeons.
This may not be a severe bug, but breaks the lore and is weird.
Slightly annoying that the hardcoded tags provided do not work correctly.
It means I've now got to scour the code and try and add conditions anywhere they could be taken prisoner.
I can confirm this on 2 different playthroughs, Free Folk seem to get access to wights, I charged 100 Crownlands Lancers into them before I realised! :'( Lucky I never un-equip my valyrian sword.
