Glad to hear it! Some Linux users have reported that the extension trying to use curl is broken for them - I haven’t nailed down a good fix, and my Linux setup is just a separate partition on this MacBook, so it’s maybe not 100%.
The palette name (as provided by the user) is “sluggified” using a lua port of Skeddles’ own “sluggify” that he uses for Lospec proper, but (as far as I remember) the raw name is used for saved palette files - I’ll look into sanitization for those too.
FWIW, I tried a different r/place palette and encountered the same issue, so I think you’re right on about the slash being the issue:
And I didn’t have any issue saving “|||| 22 PALETTE” on MacOS, so I’ll chalk that up to platform-specific shenanigans.
What I might do is fall back to saving the palette using its slug if using the actual name fails (and if that fails, something else is up).
Thanks for the report!
