Correct decision but how many times do you see that? Controversial

Perenara takes a penalty quickly and gets within inches of the tryline, the Hurricanes recycle the ball and spread it wide to Milner-Skudder who gets a brilliant pass away in the tackle. Savea just needs to catch the ball and dive over for a try, but he loses it forward over the tryline. The TMO instructs that the tackle on Savea had no arms and thus a penalty try should be given.
