I was aware of those bugs; but this is different. all those "bugs" are just symptoms (I think) of the same bug. What I described in here seems to explain them, and is there for NOT a "duplication".
while this is in part like the end gateway bug of MC-138069, there are three issues here: 1. end city at center 2. dragon respawning after a trip to the outer island 3. gateway not teleporting correctly (this is like MC-138069)
seems that newly spawned villagers are "blank" (at least, in cases where the map was generated before version 18w50a; and loaded in the 18w50a version)
