[Q1] If you remove an abbot with one ghost from a garden, we are considering that the player will score -2 points for the ghost, the same as for any other scorings during the game. Removing the abbot without penalty from the ghost seems an extremely easy way out. Is this correct?
[A1] The ghost should simply score -2 points, no matter if you scored the abbot early or not.
As a general case, ghosts should be considered in all scorings involving features or meeples during the game. Each ghost will be worth -2 points.
Therefore, these scorings will take into consideration any ghosts added to meeples:
* The scoring of a road with a Road Sweeper gift (The Gifts)
* The removal of an abbot (The Abbot)
* The scoring of an acrobat pyramid (Exp. 10 - Under the Bit Top)
* The scoring of a field due to a barn placement or to connecting fields with barns (Exp. 5 - Abbey & Mayor)
* The scoring of a feature just completed (base game and expansions)
* The scoring of a meeple with Message #8 (Mini 2 - The Messengers)
