Confirmed — once you're in the Maple 7th Day Market there is no way out, sorry you got stuck.

The market has exactly one exit portal, and that portal runs a script whose job is to send you back to whichever town the market tout warped you in from. That script was never wired up on our side, so pressing Up on the exit does literally nothing at all — no message, no warp. A relog is currently the only escape.

The fix is the same trick the Free Market already uses: remember the town you were standing in when you took the ride, and have the exit portal put you back there. If for any reason we don't have a remembered town, it falls back to Henesys, which is the market map's own listed return map. Everything else about the market (the stalls, Mr. Oh, Lung Tup, Lena) is fine — it's just the door out.

I couldn't tell from the report which part of the market you meant, and I found two separate problems, so I'm recording both rather than patching the wrong one. First: the market's exit door doesn't work. In v83 that door runs a script that sends you back to whichever town you entered from, and we don't track 'where you came from', so the door currently leads nowhere — you'd have to leave with a Return Scroll or the world map. I left it alone deliberately: the file that holds these door destinations only accepts doors with ONE fixed destination, and this one doesn't have one, so adding a made-up destination would break that rule. Second: the five 'Special Item Merchant' stalls (Mr. Oh, Lung Tup, Lena, Tae Gong, Hanako) have no stock at all — they just say their idle line. That isn't a wiring bug either; the private-server data we source shops from has no rows for them, so their stock would have to come from somewhere else. Tell me which one you hit and I'll do that one properly.

Fixed. The market's single exit door (`out00`) is a scripted portal whose destination isn't in the map data at all — in the original game it warps you to wherever you were standing when the market tout took you in. We had no entry for that script, so the door resolved to nothing and pressing Up did nothing. It now returns you to the town you came from; if that's unknown (say you logged out and back in before we started remembering it), it falls back to that market map's own return map from the v83 map data — Henesys, Ariant or Orbis depending on which market map you're in. Only the door does this: a Mystic Door or any other way out of the market still takes you exactly where you aimed it.
