Got some strange-ness afoot on a site I’m working on.
With a number of revisions built up, you can go back and forth between #2 onward as you’d expect and the later revisions are still visible in the revisions tab.
However, if revision 1 is selected, all later revisions disappear. And just to add to the confusion, this is only happening on about 30% of channels.
Not sure where to start on this one, I think you might need to take a look at the CP yourselves to see it happening.
