First of all, greetings RPG-Revolution, this is my first post!
Sorry to make it a noobish question asking for support, but I need assistance. In my game, I have a specific map that keeps causing random errors that I don't understand. I removed all scripts, and all events, and the problem is still there! I even went so far as to remove all the other maps, and it still does it. Now, I could recreate the map I suppose, but I would like to know what is causing the error so it doesn't happen again. The error is: "Undefined method  for NilClass". I am no scripter, and have no idea what that means.
Here's a link to a demo of the problem: http://www.mediafire.com/?b8oobsbuw532dqo
Just walk around on the map for a few seconds, and you will see what I mean.
