This happens when you move a material over a part but don't release.
Other parts of the model change material permanently.
Also, the UNDO button doesn't reverse this.
I'v always had problems with 'undo' in most cases, or rather, i'v never really got my head around its nuances.

I don't have problems for most part. This just happens on larger models. That's what it seems like anyway.
