Where is the module builder

[Tatertron]

So, I updated, and now the module builder is gone.

I'm trying not to have a panic attack here, but I had 3 months worth of work on a homebrew in that builder. Please tell me it didn't just get erased

It's now accessed from the right side button bar, the Books button in the Library group. Above the list of modules is a Campaign button. That opens the module builder.
