Technical issue - member mark disappeared.
Today is the second time it happened, first time I thought I made a mistake.
At around 3:20 PM today, I marked cropduster08 . I clicked on his profile, he had zero marks. I clicked "follow," refreshed, and observed that he now has 1 member mark. Later tonight I looked at his profile again and noticed that the mark disappeared. I marked him again tonight at about 11:30PM.
The same problem occurred a few months back, but I don't remember the date or the member's name.
