Another leak has arrived. I am not responsible for this, I am simply sharing it.
This time, I am here to present you with the rather recent source of Firestorm (https://firestorm-servers.com/en/) 5.4.7/5.4.8.
It's the source code itself that is being shared, and may be useful to see how they code things, give you some information on the process and you can even find many useful fixes here. (Again, I take no responsibility)
