Bad Data on Volumes

We have found an anomaly with some data from work. On a January mission we had a stockpile read at 653m

Then in Febuary the same stockpile had material removed but showed 759m
We are using the Best Fit base line, does anyone have suggestions?

@Raven_Lens - I’m having the same issues. Check my post: " Volumes at our pit are increasing?" in Bug Reports & Feedback
