So I have been trying to make a modded Aternos server with 59 mods on 1.2.12 with forge version 14.23.2847 with world set on BIOMESOP. I have made other servers before with this many mods before and never had any problems. I have attempted making multiple servers and taken out mods, tested the mods, and whatever. The server would only start if I put the mods in 3-5 at a time and started the server then added more mods but not all at once, but after that one time if I tried to start the server again it would crash when it got to the achievements. Here is the log after the crash: https://mclo.gs/TV0hYeY I never got an actual crash report for the crash though. If anyone can help please comment something because I really want to play on this server with my friend and these new mods. Of which here is the mod list:
