Again, this is not a MobHunting error:

Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.github.tnerevival.core.material.MaterialHelper at com.github.tnerevival.utils.AccountUtils.getBalance(AccountUtils.java:103) ~[?:?] at

The error is in com.github.tnerevival.utils.AccountUtils at line 103. and this is not MobHunting.
