any chance you could share a patch that demonstrates this?
Sorry, not really. This was in a very complex project, which looks totally different by now. I think the problem came from multiple sources writing and reading the same reference. Still it is mysterious to me how the IO box could show something different here. I also had the bevahiour a lot, that IO boxes don’t update, when displaying references. I keep deleting them and creating new ones, to see updated values.
