dude an entire drive on my computer suddenly got corrupted and I ended up losing all my progress on a pack I was working on. I backed up my drive a few months ago so luckily I didn't lose anything else of much significance, but it's still quite frustrating
So, for the basics of the game, you should start chopping a lot of trees near your spawn. That way, when it's night time, you can create a big base to fend off zombies. Instead of staying indoors, I recommend you go out in fight the monsters to gain early loot. If you're in danger, and you can't kill all the monsters, you can always go back to base. If you need anymore tips, I'm willing to give you more tips!
