(RPG) AI_TEXT Explorer

When the game finished loading, I got the following error message:
"FATAL ERROR in
action number 1
of Draw Event
for object ASSIST:

DoDiv :: Divide by zero
at gml_Object_ASSIST_Draw_0"

Now I don't know what it means, but I've copied it word for word so maybe perhaps you could fix it.

While this is a nice game to burn overwhelming boredom... It's a bit simplistic. Don't get me wrong, I'm not against simplicity, but I think that maybe, you could implement a bit of a background story? Anyhow, good job so far, friend. Good luck with further development.
