New posts don't appear in one topic

[DWizzy]

[edit: it must be early, I forgot to use the 'check for errors' option. The two latest messages have now appeared. Sorry ]

I have hxxp:www.baroeg.nl/forum/index.php?topic=1103.0 [nonactive] where the latest additions don't show up. New posts to that thread don't disappear completely, because they are visible in hxxp:www.baroeg.nl/forum/index.php?action=recent [nonactive], the reply page and the split topic page.

The forum is in Dutch, BTW. No important packages installed (only custom profile mod and a set of smileys)

I haven't found an answer as to why this happened - but to be honest, I didn't know where to look.
