Yes, me too.
Ever since I bought the pack 'Island paradise' my game keep freezing for a few seconds every minute or so.
Does seem fair, though. The pack is HUGE!
I checked my disc drive on the pack and it took up most of the space in that section.
How to fix this:
1. Go to your disc drive. (Or where the game pack files are)
2. I don't recommend deleting anything, it might mess up the game.
3. See anything out of place? Such as an extra piece of content lying around? Then check its files.
4. Once you check its files, look closely. There might be a bit of stuff lying around that is not needed. Like in-game purchases that you don't need or wan't.
This too confusing? I thought so, too.
