Bro, can you shut up @Jim? You misunderstood the cause of your bug, the moderation team's quite intentional and reasonable manner of response to it, the purpose and intent of this bug, and the actual state of experimental custom world features. But that's okay, no one was holding it against you until now. Quit while you're behind and move on with everyone's lives.
@Jim Because your description of the problem, how it presents and steps to recreate match with the troubleshooting that's been done by myself and others in pursuit of understanding this bug. You just didn't think hard enough and look far enough before deciding to complain that Mojang was being "unacceptable."
That issue is the actual and direct cause of this one.
@Jim Also this bug is actually the cause of that one you requested to be reopened, maybe pay a little attention and do some actual troubleshooting to determine where the two add up.
No it doesn't, wayne, you're not helping.
Even if it reduces the lag when crossing chunk borders (which I did not find to be the case, at least not any more significantly than just exploring with the output log closed instead of open), the biomes still become null in-game.
I assume this bug is also responsible for decorators not generating in custom dimensions.
