Spells: Fear

[svarien]

I have had a problem with fear spell as of late. When i cast it for the first time on a mob sometimes i get the message that the spell has worn off and then message that it has taken affect. Every time i have had this happen the mob is not feared. I know that you normally get messages like this when you cast the same spell on a mob and it replaces one but that isn't the case here.
