When I look at the discussions it tells me the wrong amount of comments that are in that discussion, like it says that there are two comments in one then when I go into it there is seven. I don't understand and it is annoying.
It could also be that some of the comments have been deleted.
Sometimes users delete their comments when they see someone else has answered the question better, sometimes moderators delete comments when they're off-topic.
And the forums and number of comments just seems to be a wreck a lot of the time, to be honest!
