When hitting a lapis ore block with a weight lens and dropping it onto a slab the item you get out is untextured.
It still places down properly and has the correct name.
This happened with orechid spawned lapis and jei cheat lapis
I was using a weight messenger lens

this is a vanilla bug - EntityFallingBlock drops an ItemStack made with (block, 1, block.damageDropped(state)), but lapis block's damageDropped assumes the thing dropping is the lapis item, and returns that meta value instead. any fix would require changing vanilla or using our own falling entity

closing due to the above, I reported it to vanilla: https://bugs.mojang.com/browse/MC-112891
