I have a tower with a trench around it. Suspended in the walls by signs I have pockets of lava. The intent was to have mobs fall in the trench, try to get me in my basement and eventually touch the lava and catch on fire. This they do, but they do not die.
I am running a mod-less server v1.5 Beta (So clearly this is an SMP game :))
I had two creepers, two zombies and a skeleton in the trench. They would catch on fire when trying to run into the wall with a lava block on it, but never die. They just sit there on fire until they move away from the block.
Is this supposed to be happening? Is this an SMP only bug? Looking for some guidance :)
