When entering the End Portal for the first time, I immidiately dropped into the void and died.

Don't know if this is because I was spawned into the wrong location, or if the Obsidian Platform didn't generate in time to prevent me falling into the void.

Either way, not fun. I had 'prepared myself' for a good fight and lost a lot of progress.

After defeating the dragon, I also noticed that the outer end portals are a bit... janky. My first one warps me to mid air around 20 blocks off the ground. To try and prevent a big chunk of health loss from this, I built a platform around the outer end portal. That didn't seem to help. Rather than spawning on it, I still get popped out in mid air.
