Minecraft version: 1.19.2
Modloader: Forge
Forge version: 43.2.0
Environment: Singleplayer
Mod name: Pumpkillager's Quest
Mod version: 3.2

I followed the instructions for the questline until the part where you do the summoning ritual for the Pumpkillager for the battle. I double checked that the ritual was structured properly, but nothing happened no matter how I did it.
