Raids spawn without villagers.

Raids spawn in an area where there are no villagers. There was once a villager in the area, but it has been dead for a long time. Giving the glowing effect to all villagers reports that it was given to 6 villagers, but all 6 are accounted for in an iron farm that is several hundred blocks away and up near the build limit. Raids consistently center around a certain point. (I couldn't find another report for this same issue, but who knows, if anyone has a solution for stopping these raids, I would appreciate! aaaaaa)
