Threads may be moved for various reasons.
For example if someone asks a question about a furnace and they ask it in a 'Recipe' forum it would be moved.
Or if a question is asked in 'Ask the Factory' and it has been answered by the community, it might be moved to the most relvent forum.

Hope this helps.
