Panic from zmachine

[aee11]

Pressed back a few times and then issued a command and got the following error:

Unexpected zmachine error:

Not a very helpful error stack huh? I must have stripped debug info when I deployed. I changed the build process to make stack traces better.

Was this after hitting back in your browser or the back/undo button?

I was hitting the back button on my phone (Chrome/Android) which undid my actions so I guess it's the undo button. Tried reproducing without any results, sorry.

Gotcha. I think I've run into this too, but I haven't been able to reproduce it either. I'll keep an eye out for it.
