Don't much like you crabless puttin' up your walls here... You've upset the balance of the crab lands. And that upsets my crabs. Sic' em, crabs!

Crabbed Ones is an Event that can trigger if the Player has a Base within 7,000 meters of a Crab Raiders owned location. It has a 10% chance to trigger each day if within 2,000 meters, this chance scales down with distance until it reaches 0% chance at 7,000 meters. It cannot trigger if the Crab Queen is killed or captured, or if the player is allied to the Crab Raiders.
Once the conditions are fulfilled, the Crab Raiders will send an assault to the player's base. This assault will consist of one or two squads, each made up of 8-14 Crab Raiders and 4-10 Crabs.
When it arrives, the War Leader will give a short speech then order the attack, causing their squad to start attacking gates and characters, and attempting to steal food from storage containers (this is often bugged in vanilla).
