Blaze Spawners Not Spawning Blazes Anymore

A few updates have been released and even now with TU28, the blaze Spawners are still not working.

I've cleared out/removed an entire fortress and left only the blaze spawner behind and even then, no blazes will spawn.

I just created a new world and when I found a new Blaze spawner, 4 blazes spawned and that was it. Haven't seen any more after that. I've gone from peaceful to easy/hard and that didn't make any difference, I've left the nether and re-entered it and that didn't make any difference either.
Restarting the game does nothing either.

Are there any plans to fix this problem? Is there any point to having a blaze farm in MC any more? I hate to see all that hard work building a Blaze Farm only to have it turn out to be a dud.
