Nope, hasn't been referenced for probably 2 months.

 Yet:

Been an issue for over a year.

This is important to understand.  It has to do with the versioning system in Fusion.  Say you have 2 designs, A and B.  A is an assembly and B is a part.  You insert B into A and save A.  That creates version1 of A.  Work continues on for a while, now A is up to version5.  You decide that you no longer need part B in A, so you open version5, delete B from A and save version6.  Yes, it is true that version6 of A no longer references B.  But, version1-version5 all still reference B.  Fusion has the ability to "promote" an old version.  So, you could go into A's history, and promote version4 (thereby creating version6).  B is back inside A, and the reference is still live.  The version6 scenario is likely the situation that you are in with this design.

What is really needed is a way to "prune" unneeded back versions.  This does not exist today.  The only way to get a "clean" version history is to copy the project by downloading/re-uploading it, or using Save As to create a new version of A (newA) that has only version1, then deleting the old A.  Then, you can delete B.

@jeff_strater Is that version pruning functionality on Autodesk's to-do list?

For years, I've been seeing people saying that this functionality is needed.

It's a real limitation to have to delete ALL your versions to get rid of a really old dependency.

And what about a setting for keeping a certain number of versions or keeping versions for a certain time?

[FrodoLoggins]

As soon as I insert something into a new design I unlink it and save. Every single time. First thing I do.

[jeff_strater]

not the experience I have.  If I make sure not to save before I do the Break Link, I can successfully delete the referenced component.  See the attached video

Yup, so if I do exactly what you do it's fine 95% of the time. Not 5%. 

Same thing with 2 different designs. Let's say I have a toolcrib that I've been working on. Then I download a collet from GrabCAD. Upload it to Fusion. Insert it into the toolcrib design. Unlink it. Save the toolcrib. Then try and delete the collete. 95% of the time I can delete the collet. 5% of the time I can't.

Hi @FrodoLoggins , If you can share logs from a session where this fails, we should be able to track down what is going on. Can you keep an eye out for this happening and respond with a log from that day?

Thanks,
