This plugin will let you edit the rust spawn points, so you can decide where players can spawn by default. This will not interfere with players spawns to sleeping bags.
Setup
Create a spawn file using the Spawns Database plugin
In console type: spawns.config "spawnfile name"
The plugin will then use those spawnpoints when a player respawns.
Usage
Upon choosing a spawnpoint the plugin will check the surrounding of that point...
