Hi there! I, myself, have struggled with getting Ghidorah to work. None of the codes would activate. And yes, I have been typing them in correctly. I've noticed others dealing with the same issue. However, I have managed to get them to work for me! Ghidorah is now happily ravaging and wreaking havoc on my ARK ecosystem!

The solution was simple. I just unsubscribed from the mod and then resubscribed again to allow for a fresh, new download. I hope this potentially helps anyone else.
