infinite pillagers keep spawning at a pillager outpost there is a raid bar as well but no village to trigger a legitimate raid, pillagers try to chase players through a nether portal, the spawn is approximately 100 blocks from said pillager outpost. no or fewer pillagers spawn when all players are in the nether
bug started when another player came onto Minecraft realms. unsure of any other details
EDIT: raid glitch seems to have stopped unexplained
