Custom Pitch (via Temperament) not loaded, not present in palette

[pikurasa]

When a user creates a custom temperament, they also get a "custom pitch" block. This block is is loads of fun.

For example, the following block was generated from:

1. Initiate Temperament Widget
2. Clear everything
3. Choose --> Equal, then "5" for value for divisions
4. Save Custom Temperament

However, when you save the MB file and then reopen the file, the block is not present on the pitch palette. It also does not seem to be loaded as code either.
