Ok this is beyond ridiculous. I am leveling a warrior. They are lvl 25. As part of my absolutely standard behavior, when my bags are full, I go back to the trading post and sell everything in my bags.
That is absolutely normal for me.
I am sure it is absolutely normal for everyone else too.
Yet, after selling a few items, I constantly run into “Error Attemping to sell”. Clearly, it’s deliberate due to some code in the game, because I never get the error until I have already sold a bunch of items.
Whatever reason there is for doing this, the real effect is to annoy people just playing the game normally.
Fix it and fix it now.
