ActiveRecord reflections reset to nil?

I've been trying to develop an enhancement to my social tagging app
(http://opntag.sf.net) and wanted to try out map.resources, so I
switched to edge Rails for a while, but end up with a really bizarre
error in which after the 3rd time I try to do a find() with includes on
one of my AR classes, it ends up crapping out in JoinDependency#build
unable to find one of my associations. After tracing my way through
associations and join building, I've discovered that
Bookmark.reflections has been reset to nil (the previous couple of
calls it was fine), and the class file hasn't been reloaded! Has
anybody seen anything like this? I'd like to track it down, but the
only place I can see where AR::Base.reflections is touched is in
#create_reflections and #reflections and tracing those produces no
evidence...

Leei-

Why are you starting a second thread about this? There were a lot of responses on the first one :-/

Sorry about that. For some reason my first attempt to start the thread
got hung up for some time. When I didn't see it after 1 day, I tried
again, and it was created right away. This thread seems to be the one
I tried to start first.
