lategameTips.4 is worded as
"Our music is by C418, Lena Raine, and Kumi Tanioka."
This list omits Aaron Cherof, even though their music was added at the start of 1.20.
I've checked all .lang-files that come with a bedrock server download for 1.20 as well as the 1.21 preview, none of the language files mentions Aaron.
Is this still an issue for you?
