Ok, so I went into the erebus, thinking the portal would be activated like it used to be, staying on all the time, only to find out that I need a second Staff. So, I get one, and it doesn't work with the keystone. I really need help with this because i have no way back other than uninstalling and reinstalling the mod. I don't know why the staff isn't wanting to work with the portal inside the erebus and I don't know what to do.

You need to fill the portal frame with leaves to be able to activate it.
The portal will also not work if any blocks connect to the back of the leaves.
Also try and make it a good distance away from trees - the portal is bugged and will not activate when other sources of leaves are nearby.

Oh, ok, that would explain it. There is a tree next to it and it might have blocks against the back, so thank you. I'll try to get it cleared out and see if that works. Thanks for the help :3
