I wasn't able to get download a version of Tinkers Construct that wouldn't crash the server. However, I think I'll just remove Tinkers Construct. Thank you for your help on finding why my server kept crashing

Tinkers Construct 1.12-2.7.3.30

I figured out what the mod was broken. Should I reinstall it to see if it works?

I did what you said, adding the mods one by one into the mods folder in my server folder. After that, I ran the Forge Universal jar

I ran Forge Universal in my folder, yet the same thing happened

Yes

EULA is true

I did use the installer to set up the server, and that should be the latest FML log

I downloaded a forge file for a server with my friends, did everything you would usually do for a vanilla server, then put the mods in the mods folder. I tried to run the forge universal file in my Server folder, but it would just be open for a little while then closes. This is for 1.12.1 Log: https://pastebin.com/8f3v8xwF
