Bodies keep disappearing from files

[dlam51506]

I've had one body disappear from a fusion file multiple times now. I tried playing through the whole timeline, and after that the body just disappeared when the timeline ran it's course.

When that didn't work I restarted what changes I made from an earlier version of the file, v17 to be specific, and redid my changes. But after I hit save and reopen that file again, having save the updates as the latest version, the same body has disappeared AGAIN. I can't keep redoing something only for the file to have bodies outright vanish when I reopen the file again. I've used Fusion for years, but if I can't even save changes for a project what's the point?

Please attach the model, old version, and indicate what you are adding that disappears.  It would be best to attach a video to show this.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

So this here is the body I've got an issue with. I've loaded the F3D here as well. The Thumbnail shows the body at least what I had before I closed out the last session, it was there when I closed this all out. But when I open the file again? It's gone. Just gone. All of the seperate parts of the body are right where they were in the file. Of course I'm having issues exporting this file all together. I can't get it to export at all, so I pulled the most recent cached file.

I do not see your model attached to your post.  You also do not indicate, or include the body you say you are adding.  Cannot do much with data.

Did you ever find a solution? This happened to me SO OFTEN AND IT'S SO FREAKING ANNOYING.

I'll design, save, close the program. Reopening to work on me and... it's gone. Steps that apply to it are still in the timeline but moving through the timeline, anything linked to it do absolutely nothing. AGGRAVATING.

Please tell me someone has found a solution to this stupid issue. I've had this happen to me so many times now that I'm about to just delete this 12 year old program. It will completely delete all of my bodies, and then when I roll back using the timeline, random stuff will be changed and modified, like filling in purposefully made gaps that do not need filling in, or just deleting entire features altogether.

I truly think people believe we're crazy and that this bug doesn't exist. I've brought it up 3 times and have gotten no where like no one knows what i'm talking about but it's a very complicated bug that isn't easily reproducible. I just have to pull bodies over to new saves to help save them. It's BS.

Crazy is that with almost every  post we have to ask people to share a file, so we have a data set to reproduce "things".

In over 3 decades of professional CAD experience as an engineer (I worked with 2D stuff before starting with SolidWorks in 1998) and over 10 years as a Fusion user I have never had stuff just disappearing in my projects.

That doesn't mean this bug doesn't exist, but it is VERY rare. Without a good dataset AND explanation of how the file got into the state, there is nothing that can be done.
