I’ll see what I can find out. My Indonesian is still only about 70%, partly because people prefer to use their own languages/dialects here. I’m tuning in to my wife’s language, plus about half a dozen others. And I can still remember bits and bobs from the languages they use the other side of the mountains here although it’s been a while since I’ve been there. I used to be almost fluent in several very obscure languages there (which, quite fortunately, are distantly related to my wife’s language so the more I tune in to the local language here the more I remember from years ago).
