Console gets spammed with "0"

[22luminary]

I'm not sure what exactly causes this and whether its due to this mod or another mod, but the console of my multiplayer server (and the logs when playing singleplayer) get spammed with just "0" multiple times a second. On singleplayer it would just be "0", and on my server's console it would be "[Startup] 0". I installed the BadStdOut mod to see what mod it was coming from and it was this mod. Here is a screenshot of my console.
