Won't let me add my Divine Magic spell

Divine Magic

Your link to the divine allows you to learn spells from the cleric class. When your Spellcasting feature lets you learn or replace a sorcerer cantrip or a sorcerer spell of 1st level or higher, you can choose the new spell from the cleric spell list or the sorcerer spell list. You must otherwise obey all the restrictions for selecting the spell, and it becomes a sorcerer spell for you.

In addition, choose an affinity for the source of your divine power: good, evil, law, chaos, or neutrality. You learn an additional spell based on that affinity, as shown below. It is a sorcerer spell for you, but it doesn’t count against your number of sorcerer spells known. If you later replace this spell, you must replace it with a spell from the cleric spell list.

Beginning this with huge thanks to the entire team for all of your hard work making this happen! Now to pass on feedback:

1. Bug in Cavalier skills selection for character creator. Alchemist Tools available instead of Animal Handling.

Lots and lots and lots of places where there are links instead of tooltips. That... seems like an unforced error :/

The cleric (grave domain) doesn't add False Life to the Domain Spells, It also adds Spare The Dying but doesn't amend the casting time & range.

There are a lot of references to the DMG in the DM section, ca we get those linked? I can start it is tomorrow at my computer, but you can just go there and ctrl-f just as easy.

In the Secondary Tables at the end of Chapter 1, the Potion of Healing mentioned in Number 8 on the Boons table is improperly tagged with the Heal spell from what I see.

Really well done with the book, I am loving it. I was so excited to finally make my war mage. However, in the process I went to add some of the new magic items from the book to the character; Enduring spellbook, hat of wizardry, and ruby of the war mage for an example. Upon searching for them, I found that I was unable to find and add them to the character. 

Edit: I believe there may be more than just the items mentioned above. I haven't checked them all, but I know the cloaks at least aren't there.

The tiny servant spell does not appear to have the referenced stat block.

I went to make another character, this time being a Sorcerer. The Storm sorcerer isn't showing up as an option.

Mind spike scales by a d6 per spell level instead of the d8s that the spell uses normally. I do not know if this is an error on your end or in the spell itself.
