Favor: Impossible Invitation Warning
When you’re about to buy a favor, you will receive a warning, if the favor will enable you to invite the character to your court or not. If an invitation is impossible, the mod will also tell you the reason why.
This mod is completely ironman compatible!
PS: The mod doesn’t check if a character is already at your court. In that case you can ignore the warning (although this way you will be able to see, if another person can snatch a character away from you via a favor).
