Doors on structures, specifically on the building we are in, will not stay locked after a restart, when locked. Once a server restarts, it resets the door to an unlocked state. This issue NEEDS to be fixed ASAP, as the game should recognize and remember player locked doors, amongst many other things. For people who are getting started, this makes it easier for players to acquire a means of relative safety to their objects without the tedious work of building a gate, when they dont posses the tools required.
So what if someone trolls the door lock obsession, deal with it. In rl, we worry about bills, so in this game, things like this shouldn't be easily avoidable.
