For some reason, the spell "Invisibility" is no longer working for my cleric of Sehanine Moonbow (domain=illusions).
When I select to memorize the spell, it shows up in the spell slot as normal. However, if I re-open the memorize spell window, the spell slot goes blank.
Resting did not help, and neither did logging-out/logging-in. Downloading a fresh copy of the domain file and copying it to my override directory did not resolve the problem, either.
All other spells seemed to be fine. My other domain abilities (elf domain) seemed to be fine.
