I've been having a sporadic problem on this site for a while, figured I'd try to post a description.
On certain posts I am unable to see beyond an arbitary reply when I am logged in. The page just doesn't load past that point. I can log out and see the remaining replies, but when I am logged in I am unable to see beyond the whichever reply is showing this beahvior (and, since the reply space is beyond it, I can't reply myself either.)
This is presently happening with the "Regret character names?" and the first response, but I've also seen it a time or two in other threads over the years.
Very odd glitch, I haven't been able to work out what predicts whether a given thread will have this behavior, or what causes any given reply to be the 'last' one loaded.
