I assume I'm doing something wrong, Unknown opcode #0

[Chris Rhoden]

Hi,

Hoping someone can help here. I am trying to start a new inform 7 project and deploy it using Parchment. Unfortunately, I can't get saving and restoring working.

I created an issue on the Parchment github page but I think there's a pretty good chance I am doing something wrong so I'll post here.

The full source of the compiled story is:

"tr.eeho.us" by Chris Rhoden

Release along with an interpreter.

The Nameless Void is a room. "There is nothing here. Not even darkness." 
East of the void is the void. West of the void is the void.
North of the void is the void. South of the void is the void.
Above the void is the void. Below the void is the void.

You can see it here: http://iplayif.com/?story=http://tr.eeho.us/treehous.z5 If you try to save and restore, you will see that it fails to restore with the error message "Unknown opcode #0" and a very high PC.

I've tried every z-machine format, blurbed and not. As far as I can tell, this applies to everything produced my my install of Inform 7.

There's a little more information for the github inclined here https://github.com/curiousdannii/parchment/issues/16
