How to reproduce:

• Start a new game
• Click the mods button
• Create bob-the-mod (the bug is present in non-bob-themed mods too)
• Click the asm button
• 🎉 Get a free segfault! 🪦

Documentation suggests [that referring to non-existent atoms)[https://github.com/RAttab/legion/blob/master/res/man/guides/mods.lm#L167] should trigger a compilation error. This does not seem to be the case.

I've tested with other atoms and it doesn't work either. (I'm pretty sure your-mum is not a system atom.) The tab title goes green every time.

For reference this generates the following assembly:

(NOOP)
(RESET)

While going through the tutorial I realized that there's a reference to the loop field which is not present in the UI for the io-tape command on extractors. Not sure if that's a documentation error, or a UI bug. The "field" is available as read-only for extractors unlike in printers.
