We’ve setup an automated server restarter every night at 04:00, it will warn players 30 minutes prior, at 04:00 and then every 5 minutes until 5 minutes prior and every minute after that, please logout ~5 minutes prior at a safe location, such as a major city or inn.
On a side note, logging out in a safe zone, as major cities or inn’s will give you rested xp, so you can gain more xp killing mobs. You can get up to 100% rested xp.
