Hi, everyone. Back again after a year.
So, now I am trying to implement buy experience for adena/anything functionality.
Player inputs amount, clicks buy and receive XP in exchange of item. In this case adena.
Everything works fine so far except when player puts in a number larger than long. Then this happens:
[27/03 15:47:58] Exception processing bypass from player crknt: npc_268447280_BuyXP
java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1

What do? Can anyone point me in the right direction?
