Ok, this problem started yesterday for me when I was suddenly told my ip address had changed. Not sure if that's the cause but thought it was worth mentioning.
I have a lvl13 & lvl21characters in AD. My lvl13 character can see and kill enemies but there is nothing to loot. They are unlootable. Same thing w/ my lvl21 char in Auridon yesterday but when I went to Grahtwood everything seemed normal.
Today I get on my lvl13 char and still can not interact w/ any enemies I've killed. I went ahead and tried Daughter of Giants quest and same thing. Unlootable. So I get on my lvl21 char and go to Grahtwood and now there seems to be zero beasts in the forest to kill. I don't see a single one.
Any thoughts? I've tried logging in/out, fast travel, ect. Nothing seems to work.
