I sort of have an idea if you guys would hear me out.
1.Give the cupboard 2 functions:
First function is the right to build within the cupboard zone (like it is now) and anyone can get access to it once they authorize with the cupboard
Second function is the right to demolish but you need to enter a passcode on the cupboard to use it,this demolish function does not work the same as the old one.The salvaged hammer gets re purposed into an infinite durability wrecking hammer that takes 20 health away from everything it hits as long as you have demolish rights.
The problem with the above is unfortunately that the raiders could demolish the original cupboard and then place their own to prevent you from demolishing or worse they would abuse it to demolish your base.
Another idea i have is to have the demolish rights linger in the area to the users that have right to the cupboard for 24-48 hours after the cupboard has been destroyed.This means raiders can’t use their own cupboard to demolish and their grieving is kept to a limited amount because the players that have demolish rights on the destroyed cupboard can still demolish things with the wrecking hammer (salvaged hammer) within 24-48 hours.
cupboard has 2 functions:
build rights and demolish rights
Salvaged hammer is turned into wrecking hammer that does 20 dmg per hit for those that have demolish rights.
demolish rights on cupboard is password protected
demolish rights linger for 24-48hours after cupboard destruction so raiders can’t exploit it.
