      Note: Not only reproducible it with an ender crystal as the host, but with a simple minecart that is ridden by an entity, thus this error message can also occur in Vanilla Survival. According to RuinsOfFeyrin this also happens in Survival with boats.

      To reproduce, summon an ender crystal that has a passenger with a smaller render distance.

      /summon end_crystal ~ ~1 ~ {Passengers:[{id:"item",Item:{id:"minecraft:stone",Count:1b}}]}

      or

      /summon end_crystal ~ ~1 ~ {Passengers:[{id:"pig"}]}

      When moving out of render distance of the item or pig, while remaining within rendering distance of the ender crystal, the output log will periodically spam the "Received unknown passenger" error.

      No errors occur when the host and passengers are swapped. I could also not reproduce it by having an item riding a pig. I'm unsure of the render distances for other entities.
