Hotfix&Update
Thank you to Sam for the detailed follow-up and screenshots. The report helped me trace several problems to shared systems used by every city:
I'm playing again, this time in Danzing, graphical bug Ledger House. I have the Ledger House built but I cannot enter the Market, the option appears when there is a ship in the city. The enterprises built as if they were not going to produce anything, as soon as I close the tab they immediately start producing at 100%. I don't know if automated trading even works at Ledger House. I set the prices, but I don't buy anything. I also don't know if it works. I sell. Manual trading still doesn't work, I can't buy or sell anything myself. I cannot add the same city twice as in this case the return ship bypasses Danzing.

Trade and Ledger House fixes
- A Ledger House can open the Market without requiring a docked convoy.
- A docked player convoy can use manual city trade without also requiring a Ledger House.
- Workplace utilization updates workers and production immediately.
- New administrator purchase and sale rules start active.
- Specific trade routes retain their amount, price, cargo target, and administrator settings.
- Trade routes can contain the same city more than once; ships preserve the exact repeated stop through travel, save, and load.
Ships and harbors
- London now uses nine deterministic, non-overlapping dock slots.
- Hamburg's outer dock slot stays inside the harbor instead of placing a ship beyond the shoreline.
- Brigs use their authored CityScene and WorldScene visuals, correct scale and waterline, regional names, and stable arrival directions.
- London and Edinburgh's Shipyard now advances from Cog to Brig correctly, with matching construction artwork and costs.
Music and graphics
- Hunted and Legionnaire (2022 Remaster) were added to background music, the Options track selector, Credits, and third-party licenses.
- Black Vortex now begins after its former 47-second introduction.
- Graphics Quality now offers hardware-aware Auto selection for Low, Medium, and High; the strengthened Low profile targets very weak PCs.
- Every city uses the promoted Hamburg visual-consistency profile while retaining its authored water material.
Additional build updates
- House construction, material purchasing, warehouse deductions, and AI/municipal housing responses were added.
- Brigs of Britain showcase fleets and DLC-aware construction were added for London and Edinburgh.
- ConvoyPanel received its responsive four-category layout, search, stable selection, and safe cross-scene focusing.
- Town Hall Missions were added with city needs, delivery rewards, reputation, mayor support, and actionable status markers.
- CityScene loading, offscreen pedestrian processing, ship selection, UI input blocking, save/load safety, localization, and multiple panel-layout regressions were fixed.
These changes are implemented in shared systems where applicable and were checked against all 18 authored cities. The full project validator passed with zero warnings, and the Windows Release build completed successfully.
Thank you for helping me improve Hansa Forever.
