Solon's Bewitching Bravura (39 Charm) mana cost..
 

The mana cost has been reduced to 20, which is apparently classic. However, there are two problems still. Firstly, the spell says it costs 60 mana still when you look at the scroll or alt+click the spell to see its description, and secondly, if you have less than 60 mana, it tells you that you have insufficient mana to cast the spell. Still if you cast the spell you lose only 20 mana, but the check that verifies you have at least the amount of mana needed to cast the spell needs to be changed from 60 to 20.

Is there any word on this? Also, is anything going to be done about the fact that Bards are regenerating like 10 mana per tick or so when meditating, which I don't believe is classic?

Bards should get 1 mana per tick standing, 2 sitting.

Meditate was just to allow scribing and memorizing songs to go faster.

Just bumping to give this attention - it's minor but presumably an easy fix, and it's still happening.
