....why would this happen at all?

Ideally, each characters current EXP levels would be individually assessed, adjusted, and overwritten to fit the new value scale. However, since every character has over thirty-five pertinent data sets, the total number of sets to be analyzed would exceed two billion (over ten billion bytes of data), making case-by-case adjustment unfeasible. Instead, uniform adjustments will be implemented, which will cause any EXP accumulated between levels to be reduced to zero for all players. We apologize for the inconvenience this may cause, and thank you for your understanding.
