One of my biggest issue with this game is that you spend hours upon hours upon hours crafting, and scavenging for resources and when you log offline your stuff isn't "locked" persay. Meaning that if you log off some one can come over and break open your door, kill you, and steal your stuff. It is highly frustrating to have spent all that time to come back at your next login and have to start completely over. Some people might say you should secure your items better. However if say i can only spend a couple hours playing and have to log off then I don't have enough time to build a base big enough to have it all secured. I understand that this is one of the mechanics of the game, but it honestly just makes me want to never play the game again. I do understand this is alpha, but i hope the dev's see this as an issue and fix it soon.
It isn't an issue, it was specifically put in. If you don't like it, play on a server labelled "no sleepers" or "non-sleepers"
