Mambo drone firmware link broken

I’m trying to use sphinx for simulations for my mambo drone using the file mambo.drone that comes with sphinx but I keep getting the error “Preparation of firmware for machine mambo failed: curl.hook/probe failed… check your path or URL to the firmware”. As far as I can tell the mambo.drone file directs to but downloading from that page simply gives me a html document saying that the requested url was not found on the server.
Does anyone know where I can find the correct url for the mambo firmware?

Thank you for reporting the issue.
Mambo’s latest version should be online now.
