Wow! That is some information.....perhaps I'm the one misinformed, but I didn't see any evidence of any changes to the greens you mentioned when I was there in December.
The best clue that your source probably was refering to another course is #2 and #6. I'd be shocked if anyone even proposed touching them.
As for the 4th, I wonder if your source had #5 in mind and was refering to the extra tee built for the Irish Open....a tee close to the O'Sullivan home that is barely noticeable.
Regarding #18, honestly I don't remember the exact year (late 90's), but the top of the Sahara bunker was lowered about 12 inches. Again, this change is barely noticeable, but I do like it. It means that while the green remains blind, tee shots hit to certain location sometimes afford of view of the flag.
Bottom line: changes to the Old Course at Ballybunion come very slowly. After the Watson review in the mid 90's, not much has happened save recontructing some bunkers, e.g., holes #1 and #3.
Sorry, Watson also rebuilt the #7 green in the late 90's.
