Plants vs. Zombies Broken Maps

Hi.

So I recently received my Plants vs. Zombies: Garden Warfare game and since downloading the required content I've had issues with broken maps where the map hasn't loaded properly, invisible zombies and an inability to attack them. I had no issue with such a thing happening before when I used to play this on my Xbox 360, and I couldn't find any issues as such posted about the game at the moment, so I thought it would be best to do so. 😛

I've tried restarting the game, taking it out of my console and putting it back in again.

I've tried re-loading the same, and different maps and it still shows broken areas on the map.
