If the activity of your wiki is very poor, the Hot Spots module is replaced with a list of recently-created articles ("New pages on the wiki"). If you are talking about the Fandom B-daman Wiki or the B-Daman Wiki, this is probably the case. You can bring it back by getting more people to edit your wiki.

Another possible reason for this is because of a a CSS/JS file that affects the wiki, but as for these two wikis, this is probably not it.
