What happens?:
Per CentralAuth, this user has 307 edits. I can only see 59 edits. @AmandaNP could originally only see a subset of edits, but then later became able to see all the edits.

All 307 edits appear in https://quarry.wmcloud.org/query/77818.

What should have happened instead?:
Edits should not magically disappear.
