Is this where you post bugs?
I'm playing Infinity Evolved: Sky block and I was trying to get End Bees. The scented hive changed to an unknown, un textured block and breaking it with a scoop crashed the client. Then I tried to silk touch another un textured block and it would crash the client forever if that block was in my inventory.
I haven`t tried it in single player.
I believe I am required to say, fastcraft is installed in the server /client.
