I'm having some trouble extracting the archives from the game Spacelords (previously known as Raiders of the Broken Planet).
Here are the files I'm trying to extract.

I've been able to extract every non Data#.packed file but I run into this error whenever I try to use the extraction script with QuickBMS

Here's a link to the extraction script I used.
And here's a link to one of the data chunks I can't extract.
I've tried using the 4GB version of Quick BMS as well as the original one for most of the data files with no success. If this is a common error then please forgive me. I've attempted to research the issue myself but I'm afraid I'm out of my depth when it comes to troubleshooting these kind of errors. I saw that someone managed to extract some files from the data chunks but I didn't see any mention this particular error.
Any assistance with this would be greatly appreciated.
