I've also experienced this. After 1/2 hour of testing it seems that if you log out near another player or are aggressed by zombies your character will be deleted. I've tried this half a dozen times so far and it seems that if you're not agressed nor near another player it saves fine, but otherwise it doesn't. Take this with a grain of salt until it's independently verified though. Gosh, that last part made me sound like a scientist!
