In the world I'm playing on, we've found 7 zombie spawners, but not a single skeleton or spider one. Mineshafts still have cave spider spawners and nether fortresses have blaze spawners as they should, but the overworld spawners are all of the zombie variety. I'm not sure if this is just really strange or actually a bug.

remember, spider and skeleton dungaons are only 25% each of the dungeons, a dungeon has a 50% change to be for zombies
I did know about the ratios, but as an update, I've now found a total of 11 zombie spawners. That means 5 or 6 should be zombie spawners. Seems really unbalanced
Just bad luck.
