I have a problem on silk spawners. When I put a sign for players to buy spawners, it becomes a pig spawner and it says something broken. Example: This is the id for a creeper spawner: 52:50 but when I buy, it say something broken and it gives me a pig spawner. Im using spigot 1.8.3. Before I also using the same version and there is bo problem. Then suddenly I have this problem. Please help me. Thank you.
