hopefully, Arthur will get something to us soon. I know we would all love a continuation!!

How do I get them healthy again?

If your villagers show a status of "Sick" when you look at the details screen, you can heal them by dragging another villager to them. Even a sick villager can heal another villager. If it doesn't work the first time, try again. Sometimes a villager will "resist" healing attempts by a specific doctor. If that happens, try a different villager. Villagers who show a status of "weakened" will generally improve in health over time unless they are sick, elderly or continue to suffer on-the-job injuries.

Whens the new version comming out?

It will be released when development and testing are complete. LDW doesn't publish dates for software releases, since unpredictable things can (and do) happen!
