Hello Phoxounet,
this change of behavior was intended. Before 1.5.0 you could essentially endlessly reroll the items on the market by quitting and reloading the game.
In 1.5 you will loose access to the items on the market after you visited a city and quit the game.
There are 2 ways to work around this:
- Quit the game right after finishing a quest, before traveling to a city
- Buy & Sell everything you want to sell once you have visited a city before saving and reloading.
It's not ideal, and it would be better if the app would save all items which are available in a city when you quit it. The current behavior is either a temporary fix until they have a solution for saving items, or it will stay this way (I guess this is more likely).
