The Hurt sounds of the mobs (including from the Mods) are completely lost, but their daily sounds still normal. I also spotted this in an older version of the IDF but forgot to report it back to you. This time I only used IDF, no audio change resource pack or data pack. Perhaps because this detail is so small that people don't notice.

Great find, will work on a fix for the next update.

Should be fixed in 0.2.4
