This is happening because there are 2 types of coins. 1 that is used on 2moons and another that is used on DK-KR.
1 2moons coin ≈ 100 DK-KR coins
If your DB thinks ur using DK-KR coins and ur client thinks ur using 2moons coins, it gets bugged
All u have to do is figure out which file determines the type of coins and then change it...
Or change the type of coins in the database.
Good luck
