Couple issues

I attached my config I'm using. Thanks so much for your time my friend, I just purchased your plugin and cannot add it to my 12 live servers yet without a few changes which I hope are useful to the popularity of your plugin  I really appreciate your time excited to get this plugin rocking on my servers soon

1. I noticed players could build around the Roadside Bunkers and grief and build and seal them in completely so no one can access. Could we make this not possible?
2. Is it possible for these to spawn inside or next to a players base essentially griefing or blocking them from building, are there any plugin checks for this?
3. **Most important request** What are the respawn times for each bunker? Say my config only allows for 4 total allowed on the map at anytime and someone loots them all at the same time, how long until these bunkers can respawn? Its a bit overpowered for my server if they are always spawned on my map. I wish they could have say a 30Minute cooldown from being able to respawn after being looted. Or a config option for respawn times of the Bunkers? Since I have super faster custom vehicles and run speed increases this would be way too overpowered for my server if they just keep respawning and always keep at least 4 active or they respawn too quickly especially on the one grid maps.
4. Also please add checks how close they can spawn to each other as I have found many time just a bunch of them in a row for easy quick looting.
