Fixed the stacking chair issue in the next update.
To enable the floor plan you need to give people the permission in the permissions table.
Code:
UPDATE permissions SET acc_floorplan_editor = '1';
To enable trading set hotel.trading.enabled to 1 in emulator_settings. (<= 1.12.0 it automatically sets to 0 upon :shutdown, Fixed in the next update).
@Zutery Unlike plus, you don't have to bother putting clothes xml in your emulator. If you want redeemable clothing furniture all you need to do is configure the sets correctly in catalog_clothing table.
