Hi. I used forge-1.12.2-14.23.5.2838-installer-win.exe to install a forge server and a forge client. I can launch the server with millenaire mod, downloaded from here https://millenaire.org/php/dlpage.php?file=Millenaire7.2.0.zip and it doesn't crash. I installed millenaire on the client and launched a world first so it would create the config files. Now when I try to join the Server it says there is a missing registry. minecraft:ataserializers. Log is here: https://gist.github.com/Gexgekko/bb5b5f4dc37e7183e741f79fa474b5d4 Attached a photo of the issue. I have tried to look for it on internet but every post comes to here where people ask for it but I haven't find an answer

No I have the same problem, I just wanted to add info

I have the same problem, I installed the server, forge and then after a launch I added my mod to mods/ directory. The mod is Millenaire 7.2.0, downloaded here: https://millenaire.org/php/dlpage.php?file=Millenaire7.2.0.zip I hope this info is enough to help us
