Reported
Reason: "Mod not working, after changing multipliers I get prompt "Abnormal data, please login again." I'll test some more as I changed both defense and damage, next I'll try each one by themselves".
Checked by myself.
I have the same Problem, you'll get an error prompt even with just a x2 multiplier.
Doesn't matter if you try defense or damage.
