[Koha] Patron renewal period settings?

We have upgraded from 3.00.04 to 3.00.06 (yes, we are slow, I know 3.2 is out, hurray!) and we noticed that when a patron's card has expired (I first wrote: when a patron has expired, but I guess if they have expired we cannot renew them, lol) and we renew it, it only renews for a period of a month, instead of a year like before. I cannot find any settings for this? Anybody know where to find it? Thanks, Marty
