It seems like there's some kind of a problem with lava placement - when placing lava with a bucket, another lava source is created at the very top of the world {-1, MaxY, -1}. I suppose it's because of the changed packet / item handling. MC clients sends a "use bucket" packet with all coords set to -1, and MCServer just places the lava there; with Y rolling over to 255, being an unsigned char.
