For those who don't know, Jhin's colour text was delayed but will be out soon

WAAARGHbobo elaborated yesterday that the colour text for Jhin is ready, but localisation issues have delayed it a tad:

Given this the soonest we'll probably see Jhin's short story is likely next monday unless they decide a weekend release is fine, but either way it's looking like we'll see the story next week barring any further issues.

Given Shen's has ties with Jhin his character bio and colour text were likely also put back as a result, so we may see that come around next week too depending on circumstances, however I don't know if there are any issues with Shen's lore specifically so just take that with a grain of salt.

**TL;DR: Jhin's colour text (short story) was delayed due to localisation but is on track to be released soon, probably next week barring a catastrophe. **
