Added Pact of the Tome as an invocation and selected the cantrips and rituals. It seems only the cantrips are showing up on the character sheet, no sign of the rituals.

They show up in the feats tab and in the character editor, but not in the spells tab.

Not to necro the thread, but I'm still seeing this and came to see if anyone else had already reported it. Really easy to replicate, too.

Adding a little more detail here:

For me, the rituals appear if my Warlock is level 1 or level 2. They disappear upon leveling the character up to level 3 and they reappear upon de-leveling the character to level 1 or 2.

Sounds like it's being erroneously tied to the availability of level 1 spell slots, which Warlocks don't have after level 2.

That's a great point, I bet you're right!

Thanks so much, that was the problem! Normally I have that switched off to keep the spell list less cluttered.
