If i read your map right Demi, the location has but one exit out of that spawn location.
According to the rules that I understand , you can not set up a clay at the only spawn exit , weather you are leaving
or staying there (camping).
What happens if the camping player leaves the spawn, and a new spawning player spawns there and decides to leave.
He sets off the clay as he is leaving the spawn .
Again, you cannot set a clay there according the rules.
You have to leave one spawning exit clear.
No time limits on how long a player can sit or camp in a spawn either .
This is my understanding of the FH server rules, please correct me if I am in error.
