New Erebus Version needs Forge 1566 for 1.7.10!
So i installed all the new stuff and after logging in SSP i haave massive Laggs and FPS drops!

normally 70-100 fps ----> after 12-30 fps!

Can you help me!

I have no idea we have changed nothing in the mod that should cause any lag.
In fact in the last few months a major re-write of potential code that could cause lag was achieved.
It may be another mod causing it. Try adding Fastcraft.

is it possible to change forge version back to 1558? because i think forge is the problem now?!
