Done Crash on starting up Stoneblock3,

i could play it yesterday and today it keeps crashing on start up. i tried Ftb laucher and MYM launcher both the same results

 

oh ok that's two of us then now, must be server side then I'm guessing

 

not sure about that i tried 4 different launchers all the same result. may be someone understands the crash-report
as i have no idea what i'm looking at

 

just went on FTB discord , it look like a the Lama Mod has some sort of Easter egg in it what supposed to happens today. with out the mod the pack starts

 

That worked for me too; thanks for sharing that info
