There is a subtle bug in the process for determining monthly ritual casting. The check on the next turn as to whether the caster has sufficient gems available is made prior to the new month's accrual of gem income. Example:

Host the game. Spells are cast at the end of month since gem cost subtraction is immediate and you had enough gems when you gave the orders. So far so good. Assume you end the month with zero nature gems. If you have a gem income of +1 nature and you had set a caster to cast Awaken Vine Ogre monthly, you should have enough gems to cast it again on this following month. However, the check to see if the caster has enough gems apparently happens right after the game advances the Calendar to the next month, but before gem income has been done. Thus the pool for nature gems is still zero. Caster's monthly ritual order is then reset to no-cast since the game (erroneously) believes that there are insufficient gems to cast it. Gem income is then done and now the pool contains 1 nature gem and the player is left to re-issue the command.

Very annoying.
