Hi! I'm testing out the mod to see if I want to add it to my server's pack, but I'm stuck at basically the very beginning, as I can't even get the portal to form!

I have tried multiple different sizes, shapes, locations, and materials. Ultimately I just used the Stone Bricks and Oak Leaves shown in the mod description, but no dice. I made sure there was room behind the portal, but that doesn't seem to have mattered, either.

Here's a quick gif I made: https://gfycat.com/hotickyborer

And here is my diagnostic information:

• Minecraft version: 1.12.2
• Forge version: forge-1.12.2-14.23.5.2838-universal
• Modpack version (links to current modlist): 1.7.3
• Mod versions: Erebus-1.0.30

I'm a ding dong. One of my players informed me that the portal creation was gated behind achievements. I'd made the staff legitimately but I just used creative for the keystone because I was in a hurry to test, haha. My apologies for the false alarm.
