Well blast it!
Naturally in the process of updating and correcting my meshes I end up having "old" and "new" versions of things on my system and I am not the brightest of people these days, so YET AGAIN! I have managed to upload the wrong version of an item.
This time it's the BEOS 5000 CPU - the version uploaded is the original "pre-updated" version and won't take the recolours - I am sending a PM to the staff to bump that particular item into the rejected bin so I can change the package file to the new and updated version.
The Tape Reader and Printer are fine, only the CPU is wonky.
It will take a day or so to correct the file, and I apologise for the inconvenience, but all will be set to rights as soon as possible.
