Discussion disappear from discussion list after branching

I had a message on this discussion:
http://community.jboss.org/thread/154006?start=60&tstart=0

and I've branched the last message, what created this thread:
http://community.jboss.org/thread/156313?tstart=0

however, the thread 154006 disappeared from the Discussions list. It
appears only at the Popular Discussions, but disappeared from the
timeline (or whatever you call it).

So, it looks like there's a bug on the Branching functionality.

I could maybe add a test message to the "journaling errors discussion"
(154006) and have it appearing back to the list.. but I will not do it
now since you guys may find a bug on it.

If you guys could also make sure you place the discussion back on the
list after you have investigated this.
