URGENT error - Results.ScorePoints variable disappeared from project

I figured out a workaround - I had to create a new results slide and reprogram all the variables on the existing results slide. Sadly the project is now going to miss the deadline.

Could someone look into fixing all the bugs that are caused by copying and pasting / duplicating slides as a matter of urgency please? It's broken literally hundreds of our projects with workarounds pushing our deadlines back by weeks. To be honest I'm pretty appalled that the 'industry standard' elearning software can't handle a function as basic as copying and pasting without breaking everything. At this point I'm considering reverting back to Adobe Captivate.
