I'm absolutely positive I went along with him, I fought blood there, but I followed what you said in an earlier comment, replaced that map file, redid the quest without sniffing out his lie, just following it completely, still didn't work, but when I with very little hope tried switching from easyrpg to original, the door is open there, checked easyrpg again, door is closed there.
no idea how this happened LOL but it solved the problem thanks
