I did work on an image from a cellphone and saved a crop of it as a tiff. I did save it in a on the fly to be created tif subdirectory. The image browser isn’t updated. I’ve seen this before but a F5 or leaving the directory and entering again mostly solved that problem. Now not. In the OS file browser the subdir and its content is visible. I opened another pl and it’s visible. Only after a restart it became visible.
