Also after reading through the submitted bugs I found out that my Grieving mother has 16 int in one save (probably the one I am reloading to due to a bugged quest) and 24 in another, not that it matters much, since ciphers (and one or two priest spells) don't get bonus AoE unless you open the spell description after every save and load, which I always forget to do. This is most certainly connected to this http://forums.obsidian.net/topic/73188-amulet-of-health-permanently-raising-endurance/
