OK, that confirms my and schlumpfs theory, sadly, its even worse than I feared. Value in row #2, reputationIndex, has apparently max value 2^7-1 (127). This index is used in at least one bit mask, so its max range in reality probably can't be changed at all. If DBC with 128 index causes crashes, here you go, 128 is too high value for system.
So you will most likely need to overwrite some old and for you useless reputation indexes.
