I keep opening a thread and all the comments will constantly shuffle, and upvoting causes a comment to disappear somewhere else in the thread.
I try to sort by Top too and it will work for a few seconds before shuffling back to whatever default there is or New, despite still saying it's sorting by Top.
Miserable trying to read one thread on here.
On top of that, every new page seems to shoot me to the top or the bottom of the full page for no reason
