tested basalt in windows 10. it seems that silk touch corrupts the block, releasing a single one and picking it up with normal basalt blocks manages to fix it. only the player seems to interact with it as a solid block. I will upload clips to show more detail and sorry for my bad english
it happens also on windows 10, you cant drop it by pressing q and disappears when interacts with another block
same for 1.10.0.4 beta windows 10
campfire, lava and soul fire don't have animations too on windows 10
