Hi! I haven't had time to fix this but I think you are having an issue another player had where one of the coordinates are simply backwards basically giving the wrong information. I'll copy and paste what they wrote.
"I found out that one of the x & y coordinates had been reversed. The screen showed X497 Y202 (16), but actual co-ords were suppose to be X202 Y497 (10)."
I hope that helps, sorry for it not being correct :( (I might see if I can get this done tonight)
