With Master Body, Cure Disease (and, presumably, all cures/removes) breaks a small amount past effective rank 64.
____________________________________________________
Effective rank 64- Can cure for 192 days = 4608 hours = 276,480 minutes = 16,588,800 seconds. (still functional)Effective rank 66- Should be able to cure for 198 days = 4752 hours = 285,120 minutes = 17,107,200. (broken)
2^24= 16,777,216

If there's a way to achieve an effective rank of 65, I sure couldn't figure out how
But, theoretically, it would be broken at 65 as well.
65 X 3 = 195
195 days = 4680 hours = 280,800 minutes = 16,848,000
which is greater than 2^24.
