HI,
Stumbled upon it by accident. I had changed the autorate rules(and it worked) but after closing and reopening HM the rules no longer seemed to work.
It seems that HM luses a decimal point on the field agg_factor.
I had entered 1.5 and after reopeing it became 15 (fifteen). The problem was reproducable (build 4854)
