I've attempted to apply v3g and the new version as instructed. Right way there was an issue with the `guidanceeffect` function being read: it looks like the built file was smashing `return text` into the next function. I added an extra line, reloaded the line, and it appears to be fine now.
I also encountered the following messages in the console, I'm guessing they merit further investigation.
