Hi, I am having a small problem with a homebrew item my son and I are creating for a campaign.  It has 31 spells attached to it in the spells list.

1. Is there a limit to the number of spells you can have attached?  I have reached 31.  Adding a 32nd causes the save button to save nothing.  I have to hit cancel to get out of it.
2. When I reach what I think the limit is (31) I can no longer edit any of the spells.  Clicking the save button just returns the screen to the same edit page and saves nothing.  Removing the 31st spell in the list makes the spells editable again.  

Thank you for your time and thank you for this great system!

Yes. 31 is the limit.
