I am on a multiplayer server and am trying to create a lava fountain in front of my door. I have it enclosed in an area so the lava won't block any routes. The only problem is that I can't get the lava to flow. I've been told that I just need to put a bucket on top of a block and it should start flowing if I've got a step layout going down around the lava, but it doesn't work, the lava just disappears. Please let me know if I need multiple buckets or am missing something. Thank you.
