They haven't disappeared: it's a mistake in the forum settings. Only sticky threads and threads with posts less than a month old are displayed in this forum. You can change this by going to user settings > general settings > Default thread age cutoff > Show all.

The strange thing is that for the other forums on the .Org it does show all threads. It's only the R:TW hosted mods where this is set to "1 month". I will pass this on to the administrators. Thank you for brining it to my attention.
