ccTouchesMoved adds object to array multiple times, even though an if statement should avoid that
-(void) ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *myTouch = [touches anyObject];
    CGPoint location = [myTouch locationInView:[myTouch view]];
    CGPoint convertedLocation = [[CCDirector sharedDirector] convertToGL:location];

    CCSprite* realSprite = [self whichHexagonTouched:convertedLocation];

    NSNumber *hexTag = [NSNumber numberWithInt:realSprite.tag];

    // If the hexagon is not in the array and not nil, it should destroy it and add it to the array

    if(realSprite != nil && ![hexTags containsObject:hexTag]){
        [self destroyHexagon:realSprite];
        [hexTags addObject:hexTag];

        NSLog(@"these are the hexTags %@", hexTags);
        }
