Bukkit

Short description about the bug/problem:
I want to have it so that a rank gets a 50% discount, but the rank before that has a 25% discount. The 50% discount rank, crafter, inherits the other rank. My multiplier groups are the following:
- skript.VIP:money:.75
- skript.Crafter:money:.66666666666666666666666666666666666666
Sometimes, after a /bs reload or server restart if an item costs 100 then it will cost 50 for crafters. Other times it costs 49.99999999999999
Here is an gif of one where it works.
