when i try and install chisel it first always asks me to do /fml confirm because forge detects the backup level.dat is being used

i also tried updating automagy to the most recent version as that seems to show up a lot in the crash report

EDIT: i should also point out that my client works fine with these mods

at tuhljin.automagy.blocks.BlockRedcrystal.canReceiveRedstoneSignalFromDirection(BlockRedcrystal.java:1061)

What in the world makes you think this is caused by chisel?

because i never had this issue until i installed chisel, works fine without

Take it up with automagy
