Hey all! Col here.
I'm here to tell you why Pandemonium isn't open.
Since the 1.9 update, the JSON code has been set to strict, and some NBT tags have changed.
If you don't know what that means, that's fine. All you have to know is that things broke, and I had to fix them.
They should be fixed currently, but there's another reason why it's closed.
1.9 added two new types of command blocks that totally changes how I can code.
Because of the new Repeating and Chain command blocks I can greatly reduce the lag on pandemonium, and probably make the gameplay better.
I'm currently in the process of updating Pandemonium to 1.9, but it may take a little while to be finished.
So until that time comes, Pandemonium is closed.
It may be unfortunate in the short-term, but it'll be worth it in the long-run.
Thanks for understanding. -Col
