spellcaster spells?

i'm trying to make supporting spellcaster spells, the ones that upgrade, but the master level spell never seems to get upgraded. The upgrade is ok cause when i subbed in polymorph it worked. I beleive i'm missing something in the spell but i dont know what.

There's a bug where, if you change the level requirement of a spell to something different then its original value, the game won't reckognize it.

For example, if you base a Master (Level 2) Spell from a Adept (Level 1) Spell, changing its requirement will make the game not reckognize the upgrade.

This will be fixed in the next patch.

For the meanwhile, make the spell require only level 1 of another upgrade (with the same name as the master-level upgrade) and, when the Master-level upgrade is completed, make a trigger research automatically the special upgrade to enable the ability.
