Hi!

Just updated FTB Revelation to 3.4 and the game started to crash on startup.
Does anyone know how to fix this?

I've tried to :
restart PC
reinstall the modpack
reinstall FTB App
reinstall OverWolf

edit;
Just installed FTB Revelation 3.3 again but I'm getting the same issue there

I fixed it, but I don't like the fix.
I copied the modpack folder from FTB-launcher and pasted it into a folder for curse forge, and for some odd reason it works...
