appears the same as: Verse Build Errors
@Flak tried to add a note about it to the changenotes, but I guess it got removed again 
They made a breaking change where your tooltips can no longer be in the same context as your class. just pop them all above the class definition and hopefully you can build again.
After last nights’ emergency-patch, I then also had to delete my verse devices from map/browser, and rebuild / re-add them and re-link everything again today… but hopefully that was just a one-off while they were trying to implement the language changes.
