Plutonium

Resxt do i need to port forward in order to make custom games with scripts with friends because any script I use results in my friends being unable to join the session using the built in plutonium party system

Resxt https://forum.plutonium.pw/topic/7438/release-mp-unlimited-sprint-easy-installation i got the script from here and my friends that try to join me get an unable to join session message

how exactly do i link the script? I have the gsc file but when I try to upload it it says it is not supported

I cant play a custom match with my friends when I use scripts but works when I play on my own
