My simple suggestion is: FIX THE GAME!!
You can't make a persistent world game with persistent death, make zombies more evil, and not fix crashes.
Yesterday I lost a month of play because the game crashed while I had 3 zombies on me.
Every day it crashes at least 3 times and I have to hope this happens at a good time.
This thing is unacceptable, if you are a serious software house you have to understand it, admit it and solve it!
