Tags grey out; they are never deleted
Reference tags such as @Image 1 in your prompt used to be stripped out of your text whenever a reference could not be read for a moment. Once removed, a refresh would not bring them back, and you had not deleted anything.
Your text is now left alone. When a reference cannot be read the tag simply greys out and explains itself on hover. Whether to clear it is your decision, via the “Remove stale tags” button.
Swapped references say so
When you replace the reference in a slot, the tag used to turn into an unexplained grey question mark, even though generation was in fact using the new image.
That case is now labelled explicitly: hovering says the slot holds a different reference and that generation will use the current one. The tag stays usable; you just know it is not the original.
Tags follow the asset itself
Reference tags now bind to the asset's own identity rather than only to the image address it had at the time. Re-generating, changing the cover, or moving storage no longer breaks them, so you don't have to go back and re-@ everything.
