There should be a block called the burner, that just creates fire.

I am using a computer with 8 GB of ram though.

**Edit**

I checked, and it's my CPU, not my ram that's being fully used. Does anybody else get this lag?

I've been having some issues when rendering a lot of pixels at once (think large storage spot), but not a lot of the pixels are moving. Maybe, if a pixel and the neighbors haven't moved in ~100 ticks, the pixel could "freeze", and not be checked for movement, until at least 1 pixel within the check area has moved, but the area it blocked by walls. See the ASCII art below for an example. M is moving, || is a wall, and F is frozen.
