I have received the " your villager feels better" message many times but the health doesn't go up. In fact most often I only get the message 1 out of 4 times in the first place and then no health recovery. I find it very odd that a researcher runs a high health risk then a farmer...very unrealistic. Although I can understand a health risk to a researcher it's off balance. Maybe in VV 2 there will be a better way of healing the injured because quite frankly this is not working well.
