Updated bundle with fixed version of model.
If we open a model that has this bug in Retera Model Studio then save the model -- without doing anything -- the issue will be fixed. Applies to 99% of models unless the model contents are truly insane.
Edit: (The above has been true for 13 years since the original Matrix Eater project that I authored in 2012 when I learned how to do computer programming. So, the issue with the model is that I created it prior to that time, when I was an MDX model artist but did not have programming skills. The model would have been made in notepad and the jumping model parts indicate a notepad typo - which we can fix with autocorrect.)
