Narrative:
While in cruise we received a crossing restriction for a fix not in our FMS. We then asked ATC to verify they want us to go to the fix they assigned us a crossing restriction for and we did and crossed at the appropriate altitude. The fix was on our flight plan; but not in our FMS. Before block out we verified all the points in the FMS so I think the fix might of been deleted when we programmed the approach.we were having passenger troubles with mask; alcohol; and vaping noncompliance. When programming new items into the FMS ensure all fixes are still in the FMS.
