Primates did not need Vitamin C since about 70 Ma (Ma = million years ago).
This hardly constitutes a "temporary" situation.  It is only within the last
5 to 10 My (My = million years) that the hominid line has evolved away from
significant fruit in the diet.  60 My is sufficient time,as I understand it
for a mutation to occur in a gene to make it dysfunctional, but I suspect that
5-10 My is not sufficient time to recover the ability to manufacture Vitamin
C, however that "recovery" might occur.
