Disassociated pipeline is still scheduled.

[eea71]

I created schedule rule for 2 pipeline. Test Pipe 1 and Test Pipe 2. I disassociated them - firstly Test Pipe 1 and then Test Pipe 2. After each disassociation I saw scheduler and refresh. The second disassociated pipe stayed still in scheduler.

Maybe not exactly, but seems to be related to #168.
