NoneType object has no attribute append ONLY ON MAC

[ArizaLuca]

This is an issue I've been asking about for a while, but today the whole issue became a lot more interesting. In working on the project on a Mac, the project constantly– upon getting to a certain distance– will come up with this error, and completely render the game unplayable.

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/routes/evan.rpy", line 445, in script
    with dissolve
AttributeError: 'NoneType' object has no attribute 'append'

The line in question that it bugged out at:

Code: Select all

show evan blink quirked frown onlayer front
    with dissolve

Doesn't really have anything to do with the actual issue.

It has nothing to do with that actual line; I'm thinking it may be the images mucking it up. (I also have a custom GUI and Layered Parallax, but I tried eliminating the Layered Parallax (code is from viewtopic.php?t=47482 and the error still appeared. However before I put in Layered Images, the GUI didn't cause this error, so I don't think it has to do with that.)

However, what's interesting and kind of the most puzzling part is that on PC, this error does not occur. So I'm no longer sure where the issue stems from.
