Someone I know made hot lava on their lot but I'm not sure if that was a graphical error or if there really is a way to make hot lava. I'm told that there was bubbles in it and things burned in it including sims. If anyone knows please help me. Thanks
The only way you would get 'red lava' is by having a graphics card error (When the water is red) but even then it still would not catch things alight.
But there *IS* a buyable fire tile. With a little effort, it could be made to burn forever until extinguished.
