Weird bug I’ve encountered a couple of times now using GPlates 2.2. I typically use two rotation files which I link to each other using the interface. What has happened is that I saved the modifications in one of the rotation files via the Manage Feature Collections window and it not only overwrote the correct file, it also overwrote the linked rotation file with the same data. Now I have two rotation files which are exactly the same… This has happened twice now and it’s a real pain to recover without constant backups. I can’t see any error messages associated with this. Any idea what’s happening?
