I know this issue was supposed to be solved but in my survival world, which I created in 20w21a, the End Gateway that is supposed to take you to the outer islands still doesn't generate for me.

I have respawned the Ender Dragon at least 5 times now, I've even clicked the optimize world option, everything. No Gateways though. I built a 1000 block long bridge to the outer islands, and the Gateways that take you back to the main island generate there, though.

I don't understand why the Gateways on the main island never generate when I beat the Ender Dragon...
