Logo icon suddenly not visible in XD prototype and also not exportable/downloadable
Suddenly, I'm unable to see or export / download the logo icon from this XD prototype, even though the logo icon is visible in the preview. See screenshot of the visible logo icon below:

Now, watch this screenshare where I click on this page in the protoype and the the logo icon is no longer visible. https://www.loom.com/share/361565a81d7d40d183b3e7a85123a90b I've been working with this logo in this prototype for 2 years, so I have no idea why this has suddenly started to happen. It started after I made a small change to the logo size, nothing else. The icon has been marked for export as well. Can someone help?
