Summary​

No time to prepare for defensive Great Holy War, none of my vassal join the war

Description​

I'm my head of faith (reformed African faith). I suddenly got a Jihad that started immediately (in my experience, offensive Christian crusader has a prep time?). When the war start, none of my vassals (all share my same faith) joined. The only other participant was a another free ruler.
On the other hand, the Jihad included the entire Abbasid empire (the Caliph and all of his vassals). The fight was really 100k vs 20k.
Not sure if this was intentional or a bug, but feels buggy to me.

Steps to reproduce​

1. Become head of faith
2. Be a target of a Great Holy War
3. War start immediately. You're all alone

Directed GHWs by a temporal Head of Faith (e.g. Jihad by a Caliph) don't have a preparation period or pledges to participate on either side, they launch instantly. Other rulers can join after it began, though. WAD.
