A Bug of Timeline, Blocker

[Anonymous]

Bug description:

The sketch including sweep path is accidentally moved after the "Sweep" feature in timeline , then the sweep feature is broken. The problem didn't appear instantly, so the project was saved for several versions in a few hours yesterday. The problem is only brought up today when I start Fusion 360.

Error: Circular dependency found: from Sweep6 to rail start. First feature in timeline: Sweep6 Last feature in timeline: rail start Total 2 features

I can't fix it by moving back the sketch before "sweep" in timeline. Their timeline order can't be changed by any method now.Further more, the other features are broken too, eg. the sketch folder and sketches disappear even I create a new sketch.

Fusion 360 is in an odd state that's not usable for now because of these bugs. My work is totally blocked, I am looking forward of the solution. 

Project file:  HeadSupport_V08A v25~v26 under this account, the dev team could find it in the cloud. 

Priority: Blocker

Env:

- Fusion 360 2.0.8624

- macOS 10.14.6

we cannot just find your design in the cloud.  We do not have access to customers' designs.  You'll need to export the design as an F3D and attach it here, or use "share public link" and post that link here so we can access it.

We are very interested in how the design came to be in this state.  It should not be possible to reorder a sketch past a feature which consumes it.  If you have any information how this happened, we would be very appreciative.

Once we have the design, we can try to fix it for you.  Have you tried just reordering the sketch back before the sweep?

Hi Jeff,

For its confidential, I shared the project link to you via private message.  

As we know, the normal workflow I did is :

step 1. create the path and profile

step 2. click "sweep" and use that path and profile to create a body

What action causes this bug in my memory is:

step 3, drag the sketch icon in timeline after sweep icon for some reason, maybe make it after another component for creating shape projection as reference, etc. , it's usually in control by stopping dragging over if you break the time logic, but this bug is an exception which shouldn't allow a sketch to be dragged after "sweep" in timeline.
