I've traced your 'Area with Celestial Fury has containers with undroppable items' thing to CtB and there's some real freakiness going on there Will also add the 'Poor woman chunks when beat up by thugs' thing
Have a look at this post Specifically:13. [gold abuse option like no other] There's a merchant by the name of Hes in WP and he sells gems, each of them costs 1 gold. Rogue Stone and any alike. EDIT: actually I found 1gold gems in other merchants as well. Fishy.
If that's your problem, find the file ToBex_ini\ToBExCore.ini and change the line Item Recharge Mod=1 to Item Recharge Mod=0-Item Recharge Mod: Fixed bugs where stackable items with 0 quantity in store files were valued at 1 gold, did not register a quantity when bought, and did not stack properly when bought
