What happened with /backup command? Or is there any other way to backup world ( I read in description about simple backups but I havent seen any commands to do so in the "book of tips".
And one other issue that might unrelated but still:
After last patch 2.0.2 I started getting huge lag in SINGLE player world, where FTB console just freezes... which can be solved by with forced shut down via Task manager, but this was never the issue before that.
I tried clean reinstall of FTB and java, but problem hasn't been solved for me. Can copy paste to clipboard as well since console is completely frozen.
