If you have already changed the image in the Midjourney Editor but cannot find it when you return to the Create or Organize page, don't suspect that the work has been lost. Midjourney's current documentation is very clear: content created in the Editor will not appear on the Create or Organize page before Upscale; They will be saved only in the Editor first.
This is why many people think that "the picture I just changed was not saved". It's usually still there, but it doesn't go into the main gallery view where you usually browse the work. This phenomenon is especially obvious when you use external uploads and multi-layer editing, because the relevant content is only visible to you by default, and it will not be automatically spread directly to the page like a normal generated image.
The most straightforward way to deal with it is:
1. Go back to the Edit page and confirm that the edit is still there.
2. If you want it to enter the Create page or facilitate subsequent unified management, run Upscale.
3. After the Upscale is completed, go to the Create page to see the new results.
Many people confuse operations like U1/U2/U3/U4 with "officially in the gallery". In fact, the display position of different stages of separation, enlargement, and editing is not exactly the same. For Editors, the key step to really getting it to appear consistently on the Create page is Upscale.
So most of the time, this problem is not that Midjourney swallowed the work, but that you are still in the editing state and have not advanced it to the gallery state. As long as you understand the saving logic of the Editor and Create spaces separately, you will not be scared by "where did the picture go" in the future.
