The brew potions aren't working, came on this morning to make a few and nothing. Can you please look into this when you have time

Was working fine earlier. What type of spell were you putting on the potion?

I was trying to cast true strike and has always worked.

Found out why. I'm in the process of fixing it.

Thank you for your time.

Potions, scrolls and wands should all work now. If you can't create a particular potion, you should get a message telling you why you couldn't. If the spell fails without explanation, please let me know. I don't like to have any spells that fail without the player knowing why. For example, maybe you cast the spell on a potion bottle that's already enchanted. It should tell you the target isn't valid.
