Problem with raid

Yesterday I got the bad omen effect and then went into a village to start a raid. I got to wave 3, and looked everywhere, but they were really hard to find. Today I came back to try and finish the raid, but I still couldn’t find them. Even looked underground.I went out of range of the village thinking they would be there, but they weren’t. When I went back in the village, all the villagers were outside like nothing was happening, I could no longer hear the horn, and the bad at the top was gone, but it didn’t say raid expired or anything. Is this his a bug or did I really run out of time? Usually it gives me three in game days to finish a raid before it runs out.
