Can't get heroes fiest to make anything.

HEROES FEAST' Syntax: commune 'heroes feast' This supplication creates a magical feast served by aerial servants for the druid and their group. Eating the feast cures poison and plague and heals some of the group's wounds. ------------------ I have tried to cast this as often as I can, but I have yet been able to get anything but the following echo from it: You create a feast fit for heroes! I can't find anything in my inventory or on the ground... Isn't there supposed to come things on the ground? I tried with a clean ground, and a ground with food on but to no avail. I hope you can have a look at it.
