MID & VOW are not present in v3.7.2 & v3.8.3
I have updated (with yarn) the keyrune lib to v3.8.3, but I have no mention to Innistrad: Midnight Hunt & Innistrad: Crimson Vow.

Neither in v3.7.2 & v3.8.3 in this github repository (try to search in generated css & sass files, but no mention).

In the other hand, the icons are present on the keyrune page.

Any clue about the missing icons in last version of github / npm packages ?
