OK, so this is salvageable as I have 2 machines and so I can copy them across. So it’s not a massive panic, but I think it’s worth mentioning this here incase it’s a bug.
I’ve upgraded to RW8.5 on both machines and on one of them all the stacks, apart from the in built ones have disappeared.
They show as missing in all projects and I can’t see them in Finder. They’re not in the trash so they’ve not been deleted, so I’m not sure where they’ve gone.
On the machine where everything is fine I keep addons on an external drive, but on my new one it’s still the default location, so this probably has something to do with it I guess.
Has anyone else had any issues at all?
