Here's my suggestion to make up for what your poor management and nyerk ups have caused:
Every 55 character in the account should get:
1 million AP
Full set of non-AP stigmas
3 bags of 500 tradeable manastones to choose from (HP 95, Attack 5, Magic Boost 27, Magic Res 14 .. etc)
100 x L120 tradeable enchant stones
300 plat medals
