Cartodb: I think an analysis broke my map

[arianaescobar]

Context

Sorry for the shitty title but I'm not sure on how to describe this error. From my dashboard I entered one of my maps (that until yesterday was working just fine) and instead of going to Builder, this is what got loaded:

With all these errors on the console:

The map is called SF Trees Import on my team account, arianaescobar

Steps to Reproduce

I have no idea on how to reproduce this error... sorry that I can't be more helpful :(

Browser and version

Google Chrome Version 56.0.2924.87 (64-bit)

Although you think it was working, there was a problem in any of the actions and it created a "ghost node". Once you reload the map it shows the cake. Do you want us to recover it?

We fixed it, but had to delete the B layer entirely. Classic ghost nodes problem (analysis was removed, but layer was not).

Thanks man!

Thank you, guys! I don't really mind if that map breaks, I reported it in case it helped to prevent that happening again to more users.

Does that happen often?
