Suggestion: trading post pick up change
Or,
1. empty your inventory before going to TP
2. get bigger inventory boxes
3. buy extra character inventory slot
Sorry to put it this way, but your inability to organise your items isn’t a reason to change how the TP works
Did you read and understand? Don’t let Azrael’s comment to mislead the issue.
I purchased items to two chars, but could not take only the items which I purchased to the current char. I had to take all and visit additonally the banker. Inconveniently.
The TP is functioning as intended.
If you could only take a few items that you wanted then you could use the TP as a place of infinite storage to store items you want to flip at a later date.
Forcing you to pick up all items prevents this from occurring, and as such should not and will not be changed.
