Please take a screenshot by pressing F2 and attach it so we can see.
Also, providing the seed and coordinates (press F3) would help especially.

Also this could always happen. I've come across it since 1.4.2. Dirt blocks (and grass blocks) have a chance of spawning grass no matter where there are (surface or not). The code doesn't destinguish between surface or cave for them.

I can confirm this (for grass) in 13w37b.

A screenshot of the bug, note the coordinates. There's a lava pit nearby so this may relate to MC-9807

I don't see this as an issue... In fact, I'd like to see MORE flora underground, personally.

Andrew Miranti

I'm neutral on the matter. On one hand, it'd be nice to see some variation underground (and it'd help make landmarks for navigation), but on the other hand, it's interesting to see the underground as this barren, lifeless and hostile place. Even the Nether has friendly (well, usually) mobs.

It's also possible this is Works as Intended (as MC-9807 implies), but I find it odd as it's generating tall grass on a dirt (not grass) block.

Ray

it is pretty odd, but it makes sense to an extent. It could be argued that a few stray seeds were brought in by some of the bats, and grew out of guano near lava.

Andrew Miranti

Which would make sense if there was all of the following:

A) Any way to access the cave from the surface
B) Bats
C) Water

Maybe then, but not otherwise.

Unsurprisingly, this carries on to 13w38c.

As far as I'm concerned, this is not related to MC-9807. As you can see from my screenshot, there is a lava lake nearby, and there's light behind my character. However, the light behind my character is from where I dug down and broke through, and the lava lake is too far away. The light level (bl and sl) on the dirt blocks containing grass is 0.

Light level aside, this should be considered unintended, even for MC-9807. Tall Grass and Double Tall Grass should only be generated on top of grass blocks, not dirt blocks.

That won't bothers me, why not? XD

The cave was completely dark when the flower generated.

I'm experiencing the same bug even in 1.7
but it has been in the game since forever

Dranitsin Roman

Djfe are you readed this?
