This usually include:

• Bug Report, where people report bug
  
• Mod Idea
  
• Mod compatibility
  
• Sub mods
  
• Other

Note: Bugs from vanilla and other mods might also get reported in here.

Also Note: Bug report usually contains a long page of player.log that is only readable for people who mods the game.
As it was previously said, it can be found here:
%appdata%\..\LocalLow\Project Moon\LibraryOfRuina\player.log

Yet another note: Modder usually ignore or abandon discussions since Discord exists
