You have a stickied thread, "Foo" in the "Old" forum.
You move "Foo" to the "New" forum.
"Foo" is still listed in the "Old" postlist, and not in the "New" postlist.
Despite this fact, however, when you view the "Foo" thread, the breadcrumbs show it being in the "New" forum.
"Foo" will continue to be shown in the postlist of "Old" and not in the postlist of "New" until you unsticky it. Once you unsticky it, it will no longer be shown in the postlist of "Old" but in its rightful place in "New."
