My log is spammed with this message, once for each page in every patchouli manual I have. (almost 400 lines for only two mods with manuals)
[Render thread/WARN]: Failed to load pneumaticcraft:patchouli_books/book/en_nz/categories/programming.json. Switching to fallback.

It gets really annoying as I am very aware that barely any mods will have a translation for the language I have set (New Zealand English) and it would be almost identical to the default American English anyway.

I request a config option to disable this, as it is pretty pointless and uneeded. Or condense it into a single, more accurate line:
Page(s) in Manual Name have been found missing translations for the currently set language (en_nz), switching those to the default.

what version? This log message was silenced in recent versions, iirc.

Patchouli 1.16.4-53.2
Minecraft 1.16.5
Forge 36.2.8

The logs were silenced sometime during 1.17. The question is: do we backport that change?

Closed because its been a year and I suspect 1.16.5 is not going to get an update
