Skylantern festival (True Fair). Nothing happens. The pawns launch their lanterns into the sky and go home. No effect, including on mood.

uh... im not sure if i can help you with what you wrote..
what was the reward? can you post the log if it generated anything?

I'm getting a crash when a ritual concludes positive with the effect of dropping spaceship chunks to mine. Linked a lengthy log below(First two game loads concluded with Boring, which worked and didn't crash. It crashed on the 3rd, which presumably succeeded. Prisoner sacrifice.) Unsure if its a bug with your mod or an interaction with another, hmm.

Edit 3 hours later: I used a standard public execution ritual that succeeded with no crash, leaving the ritual reward trigger of the main sacrifice ritual to blame so-far.

Found a small bug with the Vanilla Expanded Memes Mod. If i choose the "Drop space chunks when ritual completes" option it instead drops ancient space chunks from the vanilla expanded mod. These are neither deconstructable (only destroyable) and do not drop loot. Would be very nice if this could be fixed.

For some reason I had some hostile pawns on the map that had no apparel (like, "pawn.apparel" was "null"). They also had no name so I have no idea what happened there, if it's a bug in a different mod or some other mod uses them for something?
Anyway, would it be possible to add null checks to your mod at various places? E.g.

@Nawjak
:O that probably is a good idea. I wouldn't have to check for pawn since i'm iterating on the pawns, but I guess apparel could use null check... I really appreciate your suggestion!
I will try to address that when I get a chance to do so

@GERacht
Thanks for the bug report! Vanilla Expanded Meme you said? I probably need to look it to it..

ive finished animal sacrifice ritual, but got 0 outcome, no mood, no development points, no reward, heck even no letter after finishing it, animal died, ritual went on cooldown, and only thing ive got was the top left message that ritual has finished, thats it

@Amethyst the otter
what was your reward set to, and what was the quality of the ritual? can you show me the log if possible?
