If it does, how often? 
Just want to know.
Happens often for me.
10 times a day since the maintenance
Note sure if it is the case, i was having some random freezing and sometimes long loading due to addons, i removed all of them, repaired the game files, updated then reinstalled the addons that are working normally.
So far its going fine, except that the so called optimization and 7% improvement is gone again.
Just untick show online until the issue is fixed.
Dang, I wish I saw this before I spent a good 40+ minutes deleting my block-list and cleaning up a bit of my friends list.
So many old names >_<
lite friend list add on works for me
Not really. Lite friend only removed the bugged “extra scrollbar”, but the friend list crash is still there I tested it with friendlist open and show online enabled.
I deleted everyone in my block list and it works fine with and without “Show online” o,o
pressing both F7 and N at the same time works wonderfully to bypass crash
