A quick test confirmed that all the rotation modes now work as expected.
Thanks @red51!
What are the rotation modes? how you change them? Is there any doco on it?
I find hard to find a place where all the documentation is: there are forum posts on server.permissions, for instance, but it is all over the place.
Perhaps a top level pinned post with links to the several post where all the commands, settings, etc are would be a good start
