I thought a silked villager spawner was worth much more than 90-110 diamonds!?!?! I was told it was approx 400??
Added. Definitely not 400, perhaps 200-300 if you're lucky; nobody in their right mind would pay that much for a silked spawner .-. This is debatable. Some people say they're worth 50 diamonds, others say 500 xD Just sell it for as much as you can get for it.
You're making assumptions. We do not know who exactly has done it. So nobody should be putting the blame on anybody.
This is like, the most popular thread by a 'normal regular player' ever X3 I always refer to this thread every time I trade :3 Thanks Dan~
