Ah, yes. There is an issue with the way our system is currently counting and displaying posts, but we are working on a fix that should hopefully correct that (and allow for an infinite forum topic scroll) very soon.
In the meantime, to answer your question, I am hiding all of the missing topics in a shed in an undisclosed location. Sometimes I visit them, and read them, and laugh to myself in delight and appreciation for our wonderful community. It’s not weird at all.
