Trying to create a new promotion tree (heavy cav). No crashes/errors, but "promote unit" don't work!

[criZp]

The "grant promotion" button on heavy cavalry doesn't work (works on other promotion class units like warrior, except on light cav units because I messed with that promotion tree too). No ERROR in the database log file.

Here's the code. There gotta be something I'm missing, if anyone have been touching this stuff before and has some ideas that would be great.

Promotion tree is supposed to end up like this:

Rout                      Caparison
   |                         |
Depredation               Barding
   |                         |
Pursuit                  Charge
   |                         |
   |-----Breakthrough---------|
