Good catch, and it was worse than it looked — the quest isn't repeatable, there were six separate copies of it sitting on Teo. Nexon re-issued that quest once per world as a launch bonus, each copy gated to its own world in the quest data; we weren't reading that gate, so Teo was offering all six (plus five of the sequel). Teo now offers one of each. Live on develop, not in the published build yet.

Nexon re-issued Teo's Lith Harbor money quest once per WORLD as a launch
bonus, each copy a fresh quest id with worldmin == worldmax == <that world>
in Check.img//0. v83's Quest.wz holds twelve of them (worlds 10, 16-26,
28) plus Ryuho's world-28 settler set, and those 29 quests are the ONLY use
of the world requirement in the entire file — it exists for exactly this. A
character lives in one world, so Teo authentically offers one "Reminiscing I"
and one "II". We read the field nowhere, so all six landed on the same giver
with the same collect targets and the same 100k/200k payout, two of them
still showing their untranslated Korean titles.
