Hello,
Like usualy, I use to inspect how fine work my server with LagGoggles, and this is what happen since I added the mod More-Planet:

An unknow event subscriber seems to use an abnormal amount of time and may result to a loss of tps

Mod version: More-Planets-1.12.2-2.0.16-GC181
ModPack: FTP Revalation + Galacticraft 4.0.1.181

Here a more detailed screenshot with the complete name of the event:
