I have tried to start a minecraft server with mods for me and my friends to play on and when I start the server to start playing I can't start it by double clicking "forge-1.12.2-14.23.5.2768-universal" because then the log will crash but I can start it by double clicking minecraft_server.1.12.2 and when I join the server and go to creative and grab an item from one of the mods like a block for example, I can't place it because as soon as I place the block it teleports back my hand and after some time it dissapears from my inventory like it was air the whole time. Is this problem based on that i can't start my server through forge? And when I go to multiplayer to join my server it says it is a vanilla server even though I have downloaded mods on the server. Have I ruined something when I downloaded my server? Thank you so much for your help in advance
