More than one raid can happen in a village

Can you please upload the map where this is occurring? I am unable to reproduce on my own.

I've watched a few videos of it happening to people and it seems to be when people leave the village to fight raid (and the bar goes away) and then re-enter the village. Which they would have to do if a few of the raiders got stuck on terrain or existing builds.

Special thanks to @unknown for helping me find the cause of this issue. It looks like the problem has something to do with bells outside of the chunks of what the game considers a village. I have provided a world to reproduce the issue. If you place a bell within the 3x3 chunks (inside the glass ring), multiple raids will not happen. But if you place a bell outside of the 3x3 chunks (outside of the glass ring), you can trigger multiple raids.

Not sure if this is covered by the recent findings, but on my Patron server there was a raid accidentally triggered in a village behind someones base, it killed all villagers in the village, then raid ended. Hours later, a zombie villager was transformed and put in that village. Then, two people that did not have Bad Omen at all entered the village and a multi-raid started, ending when the single villager was killed again. During the raid, nobody on the server had Bad Omen, and I logged on to see it for myself and try to help. Will have to check if there is also a bell outside the 3x3 chunks but seemed different circumstances enough to report still.

Is there a way to tell if the bell is inside of the 3x3 chunks of what is considered a village? Want to be able to continue raids without having them keep stacking over and over. The only way to stop them was to either kill all of my villagers or break all the beds to where it wasn't considered a village anymore.

I highly recommend to stay near the bell if you and bell are in inside the 3x3 chunks because staying. It's a good idea to either immediately kill the leader inside the chunks where the bell is, or kill all the others first and start fighting the leader.
