Thanks for reporting and for providing the save file, we will look into this.

I have the same issue, but the other way around: The uranium rod recipe keeps being used although having a lower priority than the mox rod one. The process produces spent fuel but consumes from the available MOX rods.

I'm on 0.5.3e.

I have same issue.
On reactor upgrade it ran MOX recipe when it didn't have any MOX fuel present and produced spent fuel.
It now runs uranium rod recipe, but consumes MOX rods and produces spent fuel not spent MOX.
