I think , somewhere, somehow, someone messed up. If you click on the properties for the invisible wall (using the widget) you will find "Main" is looking for
the following ... "Easter \ invisible_wall.lua" . If you are like some of us you don't have any such folder named "Easter" thus no file called "invisible_wall.lua"
Guess we have to wait for some one to fix it. I don't know where one might find anything about "Easter"
Easter DLC was a limited availability game, no longer around until next Easter. Guess Lee needs to do a little fixum.
