What happened?

While checking my logs, I noticed that my latest.log and debug.log where over 70mb each after an hour of playtime
This is part of the log

[18:43:55] [Render thread/WARN] [ne.cr.po.PolyLib/]: A mod is using PolyLib's Item Data system without calling PolyLib.initPolyItemData() in its init method. This will break in later versions.

This is repeated multiple items a second, I cannot upload the log due to the size

latest.log
