Busycal link - one-way


I’m trying to link an Omnifocus task to a new event in busycal.

I select the task and do Hook to New → Busycal

An all-day event is created. If I keep it like that, I can see two way links as expected.

But I usually don’t want an all-day event, and so I drag the event to the right time. As soon as I do that, the link becomes one-way. I can invoke hook on the Omnifocus task and see the busycal event. If I click that, I get take to the right busycal event.

But if I then invoke Hook on the busycal event, I don’t see the Omnifocus task…
