Orb Evasion eats topics

[Niicola]

In the Portal forum, if I sort topics by post time, we can (at this time) count 63 topics with 13 The Clovervest Games: Orb Evasion.
However, if I sort topics by replies, we can still count 63 topics with only 4 The Clovervest Games: Orb Evasion.
Furthermore, I can find my level Gravity Challenge in the second case but not in the first.
Is it only me or...?

From time to time, I'll attempt to enable comments for that level, but then some error keeps occurring. Those ghost topics don't seem to be disappearing anymore...

Thinking about it more, even though something isn't allowing me to enable comments for that one level and instead leaves ghost topics, I also have to wonder what is going on. I cannot seem to find any pattern when sorting differently. This is weird...

I've nuked all of them now. Thank god you can select topics from the MCP even if they don't really exist.
