Path of Love "Enchant" ability no longer available on trees [Close]

[Mthec 150]

I no longer have the option to Enchant trees, of any type.  The option is still there under Nature>Enchant for grass tiles.

I thought it had possibly been moved, but there's no mention on the News page and asking in CA Help didn't reveal anything.

EDIT:  Okay forget that, I was trying to do it whilst riding a horse.   :

I thought I'd been able to do it whilst riding before, guess I remembered incorrectly.  It did appear on grass whilst riding.
