That's weird, It's the first time I see this bug.
First of all, do you have any other scripts? If so, can you please list them for me? (Their names, not the whole script :P)
Second thing, what have you done before encountering this error? Is there any steps to take to reproduce this bug?
Also, I have a text version of the script, everything is placed in 1 single script. And make sure you are using the latest version.
Take care!
