Hi, I'm developing a new plugin in 1.10 (version : 1.10-snapshotR1), and I want to replace a block when a player break a block and for this I use Block#setType(Material.GLASS) but It's work randomly. Sometime block become Glass, but sometime the block stay air. I have try to replace Block#setType() by Bukkit.dispatchCommand(...) with the "/setblock" command and the block change randomly to. I need help. Thanks for all next replies.
