我收到一个错误：
Swift/ContiguousArrayBuffer.swift：600：致命错误：索引超出范围

func buildShipYard(random: Int) {
    guard let opponentGold = camera.opponentResource.component(ofType: GoldComponent.self), let opponentTech = camera.opponentResource.component(ofType: TechLevelComponent.self)?.techLevel else { return }
    
    if opponentGold.gold >= prices.shipYardPrice {
        if opponentTech >= techRequirements.shipYardRequirement {
            opponentGold.spendGold(amount: prices.shipYardPrice)
            let selectedLocation = locations[random]
            selectedLocation.locationMenu.locationSelected = true
            let locationToBuildOn = locations.first(where: { $0.locationMenu.locationSelected })
            locationToBuildOn?.createShipYard(base: base)
            selectedLocation.locationMenu.locationSelected = false
            
            if let index = locations.firstIndex(where: { $0 == selectedLocation }) {
                locations.remove(at: index)
                print(locations.count)
            }
        }
    }
}

第二次运行时，错误发生在let selectedLocation = locations[random]行上
下面是我调用函数的地方：

for location in playerBase!.locations {
     if location.tavernBuilding {
          buildShipYard(random: mersenne.nextInt(upperBound: base.locations.count))
     } }

我每次都从数组中删除特定的索引，所以后面的索引每次都应该在边界内。
