Sorry for the late response, Patrik. I got sidetracked with other things this week. I see you already released the fix, so I installed it this morning and I can confirm that you did indeed fix the problem.
The stage connector arrows show up now, just like they used to. They don't show up in my modified stylesheet for some reason, so I'll have to change that, but they do show up in the default display.
On a different note, I'd like to send you a private email. Should I use the email address linked to by your name in the comments here, or is there another address I should use? Feel free to email me privately at myfirstname dot mylastname at devellocus.com. Thanks.
