don't forget to increase your ram!
it helps a ton, I recently installed and followed the instructions and got it to work, just started but im playin

I allocated 12GB of RAM to the server. I ended up waiting for up to 3 hours and nothing happened. I then added all the mods one by one and started the server, and then it suddenly worked.

Hello! This version is for single player. At the moment, it doesn't work on multiplayer servers. I'm working and testing with a friend on a multiplayer version, and the first thing you should do to get it working is to allocate 16GB to the server. The second thing is to remove the DAMNLIB mod and the KI5 mods, as they cause problems in multiplayer. The next step is to remove the FORTKNOX, Legacy VINE GROVE, Legacy CALIFORNIA, and Legacy LOUISIANA maps.
I use RTX 3060, 32gb ram, Rizen 5. It takes me 20 minutes to load the MP world I'm testing.

And I'll add one more thing I've noticed during testing: it's best to have the same playlist loaded and in the same order, both in the main menu for your single-player world and on the server you're about to open. Anyway, if you want to play in MP, and I don't think I'm mistaken, wait a bit. I'm almost ready to upload a stable version for MP, complete with an easy-to-use guide.

Thank you ! :o
