I think the relevant entries are "Friendly Random Drops" and "Assorted Fixes"

 

From what I read, the Fixpack should fix a random item duplication. From the documentation "One of the random loot items in TotLM was duplicated in two areas; one of them has been replaced. (ar9601.are)"

(As a side note, why does the documentation say it's TotL? It's Sea of Moving Ice in HoW)

I still haven't reached this area, but while looking at it using Infinity Explorer, I noticed that after applying the above mods, *both* AR9601,Container1 and AR200,Container7 have EXTERS1. Without mods, both have EXTERS4.

 

Is this intentional? Or was one supposed to have EXTERS1 and the other EXTERS4? If so is it a case of both Fixpack and Tweakpack applying a fix to the duplicate which results in the incorrect behaviour above?
