File deleted from _site/ during watch if not changed

What steps will reproduce the bug?

This is my minimal repro. _config.js:

import lume from "lume/mod.ts";

const site = lume();
site.copy([".js"]); // it also works if you do terser, for example, and also with css copy or css postcss.
export default site;

create a file a.js with a anything on it and run lume -w.

If you check, there will be a _site/a.js file with the correct content.

Now in a separate terminal, run touch a.js. Lume will show:

Changes detected:
- /a.js

but now the file disappears from _site. If you actually change a.js content, then everything works as expected (the file gets updated).

How often does it reproduce? Is there a required condition?

I tried to look into the code and I have no idea how this can be happening, so maybe is some weird OS-specific, thing? I've created a new project from scratch and I'm always able to repro.

What is the expected behavior?

The file to stay on _site when it changed but the content hasn't changed.

What do you see instead?

The file disappears from _site until I re-run lume.

Thanks for opening this issue. I can confirm it's a bug on Lume 1.17, sorry for the trouble.
I will fix it ASAP.

Fixed in v1.17.1.

Btw, I'm still getting errors like this, where the file disappears from _site if it's saved again but was supposed to generate the same output.

[oscarotero]

Is there any way to reproduce the error?

[fserb]

Use the exact same set up as before, but instead of a.js, do it with index.md.
If it's any other .md it works fine, but if it's called index.md (and becomes index.html), then the same problem happens.
