This isn't really a critical issue, but just so that it gets documented if it hadn't been officially noticed yet or whatnot, I'll post it here.
If a mod moves a thread (like, say this one or this other one), then when you are on the main page of the forums, the "Latest Post" column will show those threads in the original subforum they were in, not in the new one. This happens even when a new post is posted in that thread, so not just for the OP or such.
