I don't know the specific criteria for this glitch, but madora seems to be able to get exploration points in the mayors bedroom repeatedly.
I have a recording of it, but I'm not sure whether larian has issues with their content being uploaded.
Edit: If this glitch is specifically linked with madora, and as I believe I am the discoverer, I'd like to name it "Madora The Explorer"
I believe if you read the TOC of the alpha, you can upload any type of content as long as it's documented as either from the alpha or beta.
