Interesting situation. Seems like the campaign is set up chock full of NPCs you shouldn't ally with. Very few that you should ally with. So I'm not surprised that they make some unfortunate decisions regarding who to try and ally with.
It seems to me that the group may be calling out for help in the campaign. I'd tend to add a few "grey" characters, one or two of which might turn out to be "grey-good" like Aragorn in LOTR. Someone battle and life-hardened, yet can't let this young group fall for lack of direction.
Now this doesn't mean I'd spoonfeed all the information that they need. And I wouldn't make this NPC available all the time. The previous poster that said they need to learn to solve their own problems was right. But they may actually need to be taught how to do this in your campaign.
Or it could simply be that a few more hints dropped to set them on the right course may make the campaign more fun for them.
It also seems that they may be thinking of Cauldren as a place to visit instead of home. As time goes by, they need to grow to love the place so that they will want to save it. So if all their experiences are negative, this will not happen.
The campaign says that their reputation grows and they become more and more popular. Play this out in specific as you advance from scene to scene.
--NPC warns them of this or that with regard to the Last Laugh
--NPC offers them discount
--round of drinks bought for helping the orphanage
--wise old mage pats the young mage on the back and whispers "well done son."
Don't throw too much of this at them...all things must remain in balance. Just don't neglect this side of their growth in Cauldron.
