Answer edited, shows as activity on the front page, but not on the answer
The question currently shows on the category front page as "last activity 1 day ago".
However, on the question page, there is no indication that the answer has been edited by anyone.
The category feed does show it as "updated" at the time of the edit.
I don't know what the problem is, but this looks to me like a bug in the "post edited" indication.
