I created my Shaundakul Cleric Alexander Ershur last night, and chose the Protection and Air domains (which are listed as Shaundakul Cleric choosable domains). I cast a Minor Healing spell whilst preluding, which worked fine, but then the next spell I attempted to cast said that my domains were not suitable for my deity and character, and continued as I attempted to cast other spells.

Snoteye managed to fix this, but he also said that it may break again at a later date, so I decided to post a Bug Report!

For reference, my alignment is Chaotic Neutral.
