Snake Clan AI Cloak Bug

When playing single-player against AI, and the snake clan is one of the AI teams, skirmishers and Signy will go into cloak mode after attacking one of the human's territories if there are no units there. Even if there is a defense tower in the territory.

This allows the human player to ignore the attack effectively because the decolonization of the territory suspends when the snake clan goes into cloak mode. Snake clan units will come out of cloak mode and attack again if a unit enters the territory. I argue that this creates an unfair advantage to single players against AI snake clan.
