Created Issue:
Floating mineshafts generating incorrectly under shade.
under places like ravines, overhangs, and any other generated structure, mineshafts will float with a lack of normal features like chests, plus have floating cobwebs.
steps to reproduce: make a superflat world with air under the ground where mines should generate, look for a mineshaft, enjoy the glitches!

note the water falls caused due to skipping ticks.

To reproduce, use the "buffet" world generation in 18w16a with end generation. Weird mineshafts will generate under the shady areas.

I'm encountering the same problem in 1.16 Release Candidate 1. Mineshafts generating under floating islands with no chests, but do have cave spider spawners still. Will look forward to this fix

To answer the question about whether mineshafts generate through ravines, they do, but only when they are not exposed to direct sunlight. As I showed in MC-105035, the mineshafts bridge will generate anywhere with at least one block above it, but the supports and the chest minecarts will not and the mineshaft bridge will instead leave floating cobwebs.
Duplicate of MC-105035, if you are referring to the lack of supports and floating cobwebs.

Note quite a duplicate of MC-105035. My issue is referring to how exposed mineshafts get erased, which causes weird surrounding generation of the mineshaft.
Relates to MC-105035














How about giving us some screenshots?
gave screenshots, the fourth one proves it doesn't have to be in shade.
(Edit: the occasion that causes the mineshaft to generate like in the fourth screenshot is extremely rare)

This may not be fixed, but I have noticed that mineshaft no longer generate like this under trees anymore.
This is a big problem for buffet modes using the floating islands generation. Mineshafts will most often spawn in the open, no minecart w/ chests. It took 20 mineshafts before I found one that actually went into the island enough that it generated a single minecart w/ chest.
And this is now 1.14.1 Pre-2. This makes finding diamonds even THAT much harder in this type of world, limiting to shipwrecks and buried treasure for any chance at any as the floating islands don't come down far enough for diamonds to generate.
I think this is happening in 1.15 pre2, At least the floating cobwebs when a mineshaft ends up in a crevasse.
Affects 1.16 pre release 2
Still in 1.16.1
