When our reputation changes, the title of reputation tab in our profile includes how many internet points we received or lost since we last viewed the reputation page.

During that same period, I had downvoted a post and then that post got deleted. However, the total sum of the reputation change doesn't include the +1 of the deleted post but only includes the -1 of the downvote.

See the following screenshot which the shows that reputation change was 24 when it should be 25.
