For those that need help installing, the script needs to specifically go into:
storage/t5/scripts/zombie_cosmodrome
AND/OR
storage/t5/scripts/zombie_temple
We did some improvements in regards to T5 SP dedicated servers.
I suggest you update your T5 server config: https://github.com/xerxes-at/T5ServerConfig
it will come in handy for when the next update comes out as we fixed some stuff on T5 SP.
