PS. The most important bowls on this list are
T_De_GreenGlassBowl_01
T_De_GreenGlassBowl_02
T_De_PurpleGlassBowl_01
T_De_PurpleGlassBowl_02
T_De_PurpleGlassBowl_03
since they are being sold by the nearby traders (Anjzhirra and Hamal). So my suggestion is this:

- Let him ask for glass bowls instead of bowls.
- Modify the scripts to only accept the above 5 type of bowls plus
misc_de_bowl_glass_peach_01
misc_de_bowl_glass_yellow_01
and maybe a few others that look like glass even though they don't have "glass" in their name.
- When Neel asks for the 5 bowls, add 5 such bowls to the inventories of Anjzhirra and Hamal (in case the player has already bought and lost the original ones).
