I was out Duoing with my friend at Crauchon Grannies in Emain, right after getting DD procs put on weapons. I noticed that one kill we received no exp when my proc killed the granny. I continued to watch and noticed that a few kills that my hammer killed the granny also resulted in no exp.

Is this a known situation? was it the weapon procs or just bug?

SO I have done some further testing. It does not appear to be weapon procs, but it does appear that Granny Mobs at Crauchon in Emain have a couple bugged spawn points. The Granny that spawn closest to the keep door seem to have a chance to grant no exp.

I have since killed a few granny that died to the proc and still granted EXP. I have killed a few grannys with a weapon without a weapon proc and gotten no exp.
