Ok, I've completed everything else, but I am officially at an impasse.
I have one final achievement left, that appears to be unachievable. #30 says to "reclaim your body from Elize...", but there seems to be no way to get her to claim it in the first place. She no longer wants/tries to possess me.
I've tried every machination I could think of, without effect. I suspect I missed her window of opportunity.
It's frustrating for a completest like me to no be able to complete everything. Am I missing something?
