- happens on Mac Sequoia 15.5
- Opened an existing working document, duplicated a ‘frame’ to work on it. As soon as you move it to a new place it locks and disappears from the side bar. It si still in teh workspace but you cant select it.
- Thought it was because I was on an older Mac OS – so updated. Same issue.
- Tried rolling back to older Sketch – but now when I open that file I has ‘updated’ and is a mess.
Hi @Relish,
Thanks for reaching out—this report has me curious, and I’d love to dig into it further.
Could you share a copy of the document so I can take a closer look? If you’d prefer to keep it private, feel free to email it to productsupport@sketch.com.
I haven’t been able to reproduce the issue on my side, so seeing the document directly will really help.
Happy to take it from there 
I was seeing this too, and actually why I came here. I closed the document and reopened it and it was all there in the side bar again. Definitely a memory bug or something.

Thank you @jstrellner
I will try to do some tests to see if I can catch this. If you have any tips or steps I could try, let me know.
Cheers,
Hi @Cris,
In my case I was making mocks in 1920x1080, and in the end I was 13 of them. Lots of layers, but I think what might have triggered it was doing a find for layers that were in a qr code, so there were hundreds in a group so that I could change the color.
I think that “find” was ultimately what got me to a case where Sketch was really struggling and beach balling for 5-10 seconds while it searched or I applied color changes. After going through that is when I noticed that there were only 5 of the artboards/frames showing in my side bar.
Initially I thought that I had somehow grouped them together because it was random which one were there versus not. I moved them around, I cut and pasted them to see if that made them appear again, went through the right click menus to see if there was something, and in all cases nothing. Then after I saw this post it occured to me that maybe it’s just an error so I closed Sketch entirely and then reopen it and they were back in the side bar.
For reference:
Macbook Pro - M3 Max w/64GB of memory running Sequoia 15.5 (2TB disk with 1.32TB available). Sketch is Version 2025.1 (203044).
Hi @jstrellner 
Could you send us a copy of the affected document so we can dig into this further? For privacy, please email it to productsupport@sketch.com.
@Relish — same goes for you- we’d really appreciate it if you could do the same.
A sample document will help us investigate more thoroughly this report and understand the bug/logic behind this.
Thanks
I’ve shared it with you.
