You were right, and thanks for saying it — this was the third report and I'd been fixing the wrong thing. The menus were already translated, but the combat log wasn't: 111 messages, all hardcoded Korean, and that's the text you read most while playing. Fixed and live now. Hard refresh (Ctrl+F5) to get the new build. If you spot any Korean left anywhere, tell me and I'll patch it today.
Hugely helpful — thank you for coming back with specifics. Where things stand: inventory is now the full 42 (6×7); the combat log is fully English now (that was the big leak — 100+ hardcoded lines); and auto-hunt no longer drags you between maps — it stays where you put it, your call which zone to farm. Your smarter auto-sell idea (only sell when base value ≤ your equipped base value, keep the best per slot) is exactly right for the late-game Hero-item clog, and it's next on my list. The two spots in your screenshots — the enchant-scroll tooltip and the browser tab title — I'm re-checking right now and will patch today if any Korean is left. Really appreciate the care you put into these.
