Мне кажется у мя с маппингами что то не так, так как я беру маппинги с 1 build 1.21.8 ->

Пожалуйста, авторизуйтесь для просмотра ссылки.

, а legacy launcher скачал мне ластовый билд. Мб есть какие то утилки, которые вытащат маппинги из джарки моей версии?



PS маппинги не правильные были, вот нужные ->
