Story Point Estimate missing from Estimation Statistic drop down

[Andrew Custer]

A few days ago Story Point Estimate disappeared from the Estimation Statistic drop down on Board Settings for both our Kanban and Scrum boards. There is now a listitem called Invalid Field 'customfield_10116' for Scrum, and  Invalid Field 'customfield_10178' for Kanban. I believe some how a field(s) got deleted but I don't know what it was so I don't know how to fix it. 

Does anyone recognize this and know an easy fix?

One of your admins deleted the field that had those IDs.  You should reconfigure the projects and boards to use another field that still exists.

Note - those old fields may well have been named "Story Points", but they were just simple numeric fields.   I suspect your admin might have been doing the right thing - getting rid of duplicated and unnecessary fields!

Thanks Nic. I'm still not clear why it would make the listitem Story Point Estimate disappear when that field is actively associated with the project. I don't understand the relationship. The field with ID=10116 was a field used by our merchandising team to track product photographing (not exactly sure what the name was, but it came between two other fields related to photography, so making a leap of faith).

Also, I'll begin to research how to reconfigure to use another field.
