One thing is for sure, the map is abandoned. This happens a lot these days...There's a long list of cool maps that where never completed/developed.
I leave it up to you

. Like you said, making your ORPG is hard, its much easier to have something and work with it. Either way, I don't know much about maps, you know better...DO what you must just create another cool RPG map

I'm fine with that!
Even without that, you did find the fixed model, right? So if people have a problem they do look at the comments and find that someone has uploaded a fix.
