As of last week, my DM had an item that allowed my character to cast Bless; now the ability to cast that spell through the item is gone. Blinding Smite is on DM's homebrew item and available. (Mother Superior's Rosary Beads)

I tested this again by trying to add bless as a spell to an item I made and it still doesn't allow Bless on my character sheet. The item I made is also equipped with Blinding Smite which isn't appearing. (Avo's Tear)

I've attached my character sheet for ease of access.

There is an issue with multiple items granting you the same spell, the system will only show one instance of that spell.

Try removing all copies of Avo's Tear and Mother Superior's Rosary Beads, and then adding just the Rosary Beads back in to see if Bless shows up.

Thanks! That worked for Rosary Beads. I tried the same thing with Avo's Tear (just the sword) and Bless isn't appearing on that one. The others are though (I'm using Exalted to test them all).

Okay, same problem then.  Any time you equip two or more items with the same spell it breaks.

This came up a couple of days ago so DDB are now aware of the issue, but for now you'll have to track duplicate spells from items yourself.

You need to reload the page after you remove an item for the spell to show up on a remaining item.

Just tried that as well. Only using Avo's Tear and Bless is the only spell of the 4 missing. 

It's Bless that's missing for all 3 forms of it. Weird.

I appreciate y'all's help though. It's not going to be used any time soon; I wanted to test it out. Might have to be something the player tracks. 

Just to be sure, see if clicking the Inspiration box twice and then reloading the page helps. (It's a method of reloading the character sheet's data cache, much like bumping the character up a level and then back down.)

Nope. And now Bless from the Rosary is gone again. =|

After some digging I found that the Potion of Heroism also grants Bless, causing the same conflict as mentioned earlier.

So that's why... Zach_harrison3, try removing the Potion of Heroism and see if you get Bless back.

I did some testing. It used to be that you couldn't have more than 1 of the same magic item that had spells with charges, or else things got very messed up (duplicate spells, charges applying to both items, etc.) But I noticed that 2 Sending Stones in inventory both have Sending show up. Then I tried 2 Wand of Magic Missiles and those also work, and keep their separate charge counts.

Maybe something that was done to fix that bug caused this new bug with different magic items that grant the same spell? I hope that can help the devs figure out what's wrong.
