Error code

[willy0227]

I have built a game as my final project for a class. For some reason it crashes at random times. I can't seem to figure out what is happening. I also have no idea how to read the error log. Could someone please help me figure out what I need to be looking for?

Error during simulation.

Looking at the top line, which is usually the actual cause of the error:

edu.cmu.cs.stage3.alice.core.IllegalPropertyValueE xception: edu.cmu.cs.stage3.alice.core.question.list.ItemAtI ndex[world.keepScore.__Unnamed0__.__Unnamed2__.__Unname d0__] does not have property named color

It looks like the world has a list named keepScore and at some point the program is trying to read or write to the property "color" which does not exist.

I would save a copy of the movie before you try to find and fix the error as sometimes the movie quits working entirely.
