Raid Finder bug?

i went to que on LFR when we entered there was no monsters. wtf is happening?

Perhaps someone in the group already had a saved instance ID to that raid.

on raid finder? doesn't raid finder have different raid id from normal?

Yeah,that happened to my group too

Since the update, ToT raid finder is not spawning any mobs or bosses.

que'ed and entered Raid finder ToT today... still no mobs :/
