Infinite Wave 1 Raid

Not too sure how this started; all I know is that the raid goes on forever once you kill all the raiders

I've checked, and the boss bar only continues to go up once all raiders are dead

This was taken on a third-party 1.20.4 bukkit server with no plugins or data packs that change or modify raids
All mods used were client-side only

I've had this same issue for about 3 raids now, each of which forcibly stopped with the disableRaids command

Side note: I do not know what future update means, and I'm assuming it refers to after 1.20.1
