After I read the changelog for Minecraft 1.6, I saw that one of the few items that were fixed was beds in the nether. However, when trying to sleep in one, it explodes. Is this purely intentional, and does this happen in SMP (can't confirm now)? If it does explode in SMP, can I disable it (the explosion) for beds only, in case some griefer does this?
EDIT: Since it happens in SMP, is there a mod to disable this? Even if the bed kills them (the griefers) they still can go into the portal and wreak havoc in it
