I was using forge 31.1.37. which was stated as the latest forge version on the aternos website. I played for a few days with this version and 3 other mods. But today i get a error saying that i am using forge 31.1.39 which i did not instal neither on my pc or the server. My server crashes when i use it because it says that the world was saved using forge 31.1.37. and the new forge is incompatible. I cant install 31.1.37. on the server again because the option is no longer there so i have no idea what to do.
Here is my LOG: https://mclo.gs/Zj81fFh
My server name:Thebenju.aternos.me
My username: TheBenju
Thank You.
