WAIT!
I ran into a problem. I had 3 inscriptions in inventory, had not yet hit the give button. I gemmed the new goal. I went to sister, sister and hit give. It registered the 5 I had just gemmed, but not the 3 I had in inventory. The ones in inventory are now gone and the give button is stuck at five. It just hornswoggled me out of 3 inscriptions.
I'm going to put in a support ticket, but for those of you contemplating this, don't do it yet!
