not a valid array
 

when i use that predefined door, sometimes it will show up not a vaild array error box. it wont let me do nething but when I press about all the buttons on the keyboard pics1.png fills the whole level and the others that are currently open in the editor.

how bout some info here.....it happens 2 times a day

When does the error window popup?
when you click on the npc icon, drag it onto the
level or when you play?

when i click on the door and click it on the house and then it happens!
