Hello.

There is a suggestion to add a new method API

        private bool isEntityInZone(string zoneID, BaseEntity entity) => IsEntityInZone(zoneID, entity);
        private bool IsEntityInZone(string zoneID, BaseEntity entity)
        {
            Zone zone = GetZoneByID(zoneID);
            if (zone == null)
                return false;

            return zone.entities.Contains(entity);
        }​
