scanning the tp2 i'm not exactly sure where the issue is at....

******************
change-log on the file indicated it came from SETUP-NEJ2V694.TP2

Ok so its a mod added item.  Nothing particularly wrong with that.

Found the two patches in the Detectable Spells macro/function and inserted a ton of PATCH_PRINTs to see what's going on.

Turns out the effect index for the last ability effect is set to 15 instead of 14.  the value jumped from 13 to 15.   Other than assigning text to the item when it was originally copied over there was no patching done. Thus its safe to say that the item in question was incorrectly assigned at creation.

Nothing wrong here with the quest pack then.   Off to report at NEJ  (if I can find where to report)
NI is being a jerk and not letting me reassign the index # even tho it points to the effect exactly 0x30 away from the previous ability's effect -- gonna have to reassign with weidu I guess.
