I've made some NPCs that offer traning services. All of them work fine except the ones that offer Block and Enchanting training.

The problems are different:

* The Block training is offered (the training window is displayed, and you can buy training lessons) but the NPC won't say a word
* The Enchanting traning is not offered (the training window is not displayed) and the NPC won't say a word, either.


I've followed the same steps for building these trainers than what I've done for the NPCs that offer other training lessons (that work perfectly) and what works for the other skills, doesn't work for these ones. Nothing of these works:
* changing the NPC that trains in those skills (to test if there was a problem with the NPC)
* changing the place where the training is offered to a place where other training is offered without problems (to test if there was a problem related to those places)
* changing factions of the NPC offering training (to test if the dialogue was conditioned by factions, other than the JobTrainer ones)
* changing the trainer class (to test if there was a problem with the Master class of those skills)

I am running out of ideas, so if you think of anything, please, tell me
