We got to the last round of a raid and had only one raider left. Then, as we were searching for the raider, the raid bar disappeared. When we found and killed the raider there was no celebration because the raid bar had disappeared, so it never said "Raid - Victory".
This is a video illustrating the problem: https://youtu.be/GPGfLlO-1DU

It seems likely from the video that your raid timed out, since it stops on its own after a few days to prevent it from going on forever if the player can't find all the raiders.
