FOSS gamedev and creative worlds

Today I generated a new world with 0.4dev-20120320, and found a lot of half-generated trees (they have no leaves).
A screenshot I made (I didn't remove the leaves, they weren't there in the first place):

Thats a bug since 0.3.1

Well, It had never happened to me : /

I've seen this bug too. It seems like Herobrine plays Minetest too. D:

He looked at github

I think the problem is that the block with the ground is generated before the block of air above is generated. Therefore when the tree is added to the ground there is no memory allocated to put the top of the tree. So to prevent this from happening you would need to make sure that the block above is generated first, before adding trees. Or maybe you could save information about the tree-related nodes to be added to the above node when it is finally generated. Or give blocks with a higher y-coord are given a higher priority in the generation queue.

Never happened to me, sorry. :/
Tested locally + multiplayer.

I've seen the old bugger before, it juust happens though.

lucky lucky calinou :)

Last time I've seen this bug was when I joined Minetest (July 6th 2011, so it's pretty old = 0.2_20110704). 0.2_20110731 fixed it, apparently.

No, it exists in all versions between then and now, and probably even all the way back to when trees were first added.
randomproof's answer about why it happens is pretty accurate.

I have one of those, I just thought I didn't finish chopping it down.

Okay, now go tell celeron55/make a patch. 8)
