Pixelmon reforged

Hello, I am trying to start a pixelmon reforged server with friends on 1.12.2 and the latest version of pixelmon. I can install the mod onto the server but everytime I click to start the server it crashes halfway through and says saving so the server never starts. I Tried changing to an earlier version of pixelmon and the same thing happened. I don't really wanna try going to an even earlier version because there would be a lot less content. I have the log If that helps https://mclo.gs/4ykExy5 . Hope you could help and thanks anyways :).

Nevermind I fixed it by changing the version of forge between the different 1.12.2 ones. Thanks anyways
