I am asking this here, because only the Science Fiction & Fantasy site seems to be affected. The other stacks I am active on are behaving normally.
For the last few weeks (at least) every time I have a new notification from SF&F, it pops up a number showing how many new notifications I supposedly have; and the number is almost always wrong, always from one to three larger than the number of actual new notifications. (I initially thought that the number was always wrong, but it may be correct, if I already have Stack Exchange open in a browser when the notification appears.)
Is anyone else experiencing this? And does anyone know what is going on?
