After upgrading from 175 to 181, Mana Pylons no longer give the level boost to the enchantment table. I have 2 next to it, and it acts as if there isn't anything around it at all. Tested on my server and single player.

Still works for me. Are they one block away?

Okay, you're right, and that makes sense. I guess this can be closed. Is this something that changed, or has it always been like that? Cause I could have sworn it worked fine with them right up against the table.
