I noticed this too. I thought the holes looked more like difficulty 3 (normal) during the 2 rounds I have played. Even though it shows as difficulty 4 on the Tournament page. Then again, since the World Tour is set to difficulty 3 (normal) maybe my mind just thinks the holes look this way now.
Thanks for putting up a tournament, but take care of what is important. Always family first.
If I can help in any way, just let me know. Well except for diaper changing
