Found this in the DW20 pack

Found it interesting, any idea which mod adds this and why?

Use WAILA to see which mod the item comes from. That will provide you with an answer.

I've seen this in denLib.log. Not sure if that's just a general logfile that everyone uses or if it's specific to the denLib core - that would narrow it down. Possibly Plugins for Forestry.

Factorization does it
He also did that for Diamonds

first time I saw this, it was fun. the second time I saw this, I didn't really thought much of it. but now seeing it for the 3rd or 4th time... it's getting old

Like most jokes then?

Yeah i just saw a different one today in the launcher log, there were like 4 lines of it. Does not come across as very mature.
