Ender Dragon Not Spawned

Created world in 18w44a now in 18w45a. Went to end in survival and ender dragon is not there. Ender crystals are, endermen are, but no fountains and no ender dragon.

When I relogged and the fountain was there AND open as if I killed the dragon already. There is no egg on the fountain either. But the End Gateway Portal is not anywhere on the island, I am further confused. Everything else is normal.
