Hi. Due to an unintentional interaction with Abyss content, we have temporarily disabled the 'Additional Monster Projectiles' modifier in Private Leagues and it will not be available upon creating new ones. It will stop working in all existing private leagues and the modifier will be reenabled once we have a proper solution. If you want a refund for the private league created with this specific modifier, please contact our customer support team at [email protected]
Edit: the temporary fix for existing private leagues is now live.
