Another late night testing. So far so good! I only have two problems, one minor one which I will show here:
The bug happens when a trader is supposed to return for wares you have a timeframe to complete. Once the trader returns, there is an error for ‘no player id’. See the Image below.
This does not affect if you do not have the wares. The trader will return and state that you don’t have what he needs and will try again later.
This also does not affect immediate trades for items you already have in stock.
