Error ruins my progress. Twice!

[Elayness]

I get this error in my games every so often. It makes some aspect of the game unplayable, and if you cannot resolve it, you lose your progress.

Error:
TypeError Cannot read property 'Hight' of undefined.

This is really bothersome, and a rage moment. I just dont want to imagine what it would be like if I worked longer on those games...

Anyone who has an idea on how to resolve this, please reply...

It actually says "height", not "hight" in your error message. Your error is identical to the one in the RMW thread.

Have you updated your plugins to the latest versions and looked whether that's fixed in them?
