Hi, I'm making a mini-game plugin and it sets the floor (64x64 blocks) to air, then after 5 seconds, it re-generates the floor as wool blocks (with different colours). My code works, but it's *VERY* laggy and nearly crashes the server (it does freeze the server). Is there a way I can do mass block updates with minimal lag? Currently I use block.setType() and block.setData(). I tried sendPacketChange or something, but that crashes the client.
