I don't know if anyone else has had this issue, and i don't know if it is just because of the latest update because I've never experienced it before. But i figured, if by some chance the community is not yet aware of this I should post it. For some reason the trees that i planted (only the oak) replaced some of the materials, glass and wood, that i built my shop with. Anyway, i figure that if people are not yet aware of this they really should be in case someone accidently did this and it affected something more valuable, like a block of diamond.
This is a known issue, tree leaves can replace pretty much any materials when they grow. I'm not sure if there is much Justin can do to program it out, but i believe for the small amount of disruption they cause we can learn to live with it.
Unless it's a new glitch, I don't think it replaces glowstone... either that, or I've been really lucky with my tree farm this whole time. I have 100 trees in my basement which are capped to grow only 9 blocks high, so they don't get big branches. Each tree is capped with a glowstone block, and I've never seen any of them get replaced with leaves.
Tree leaves will replace adjacent transparent blocks, since the leaves will never go above the cap (they are limited by it) they cannot replace the glowstone.
This is weird. This guy got his wooden plank replaced. And i got glow in the tree farm wall to the side. And the top as well
Not cool... maybe it IS a new glitch... I'll have to check my tree farm when I get off work later tonight.
