Made an update to v0.39 for the time being.
Same as last time, haven't really tested but there should be no issues, compared with current game scripts it mostly replaces “Celia” with “Mom” where it makes sense (though it seems I have more files in my version).
…Why does OP link to v0.37 patch, anyway?
Technically he did, it just that patching it as intended by the dev leaves protagonist calling his mother by name all over the script, which is quite unnatural in any culture I'm familiar with (…though there seems to be an alternative opinion on this part, based entirely on speaker's hometown customs apparently).
