Call of the wild (Dryad lvl 3 ritual) not working

[Wintermute]

I used it in a grove a gaia aprox 20 turns ago and as of yet absolutely nothing has happened. The desc. says that units will begin spawning in all forests not owned by the caster, but nothing at all has spawned, why is this.

At first I thought it might be because the spell desc. says it can only be cast in an ancient forest or any sacred grove, but if the fact that it was cast in a grove of gaia were to prevent it working it would have just made it immpossible to cast (greyed out) the spell.

I also have not since improved the grove of gaia.

Is this a bug, or am I just being dumb?

P.S. There is no entry for the dryad class in the manual at http://www.illwinter.com/coe4/coe4manual.pdf

P.P.S. Is the earth mother worth it?

The summoned creatures are independents so thats probably why you haven't noticed anything, you have also probably fought some of the creatures which were summoned by the ritual.
