I have a Multiclass Character Inquisitor and a custom class both with a 3/4 BAB. He is now eigth level and his bab is being caculated as 5 when it should be 6 this effects his iritive attacks. Could this be a rounding issue in the program. What I think is happening is that the prgroam is taking the 3/4 bab from each class and adding them together and rounding down instead of adding the class levels together and then multiplying by.75.
