except Harold's???? whats different about him???? this is the weirdest bug I've ever heard of. have you ever messed with the files before?
I want to say that actually cuts it out, but maybe it's the boosted health potion? I know it's not the cleansing water, love potion or cookies since I started a new save and grabbed all of those too a while back when I found something I missed on my main save to speed up early game like you did. just not the boosted health potion. do you have a save from before you grabbed the boosted potion? if you do, try and grab either regular or enhanced and see if anything changes. if not I am... really lost on what the fuck is going on.
