Chunks don't load properly while riding a boat.

Did you try to make this bug happen again? Sometimes random chunk bugs can appear, are you sure this is the boat causing it?
Also when you see a chunk bug, never go inside it, it's "normal" if you fall into the void.

I have this problem, too. Chunks simply fail to load fast enough. If I don't come to a complete halt and wait a good while, I fall off the edge and cannot recover.

No problems while walking/running.

Happened to me on 18-Dec, also riding a boat. It's bad design if the program treats an absence of data as data of absence (void). The "void" that causes death should be either a hard-coded boundary or a data-driven boundary, but something explicit either way. Players should not be randomly killed (and all of their possessions destroyed) simply because a server/ISP is too slow to deliver chunks under their boats.

Not going to happen as people have found ways to build machines, arenas, etc that use the void. Adding a boundary to the void would break them. However I agree on the death issue.

He's not saying there should be a literal boundary, or wall, in the void, only that it should be clearly defined where it begins, and that the game should not assume that any given space is a void simply because it has received no data stating otherwise.

Maybe the game shouldn't allow you to enter unloaded chunks.
