Every once in a while I'll get negative multiple enemy bonuses. Is this expected behavior?
For example, I got this while fighting two firery dire wolves
[08/09/10 18:14:54] Gained Spiritist experience: 9996 ( 252 from multiple enemy bonus )
[08/09/10 18:16:12] Gained Spiritist experience: 4622 ( -159 from multiple enemy bonus )
Took on another two and this time they were both positive
[08/09/10 18:41:01] Gained Spiritist experience: 11920 ( 367 from multiple enemy bonus )
[08/09/10 18:42:01] Gained Spiritist experience: 10768 ( 81 from multiple enemy bonus )
