It's not really a bug, rather a design mismatch due to all the recent changes...

Btw, I need to say that I like most of those changes a lot, especially the "purple for money", Hall of Legends, Spoils of war and the removal of Jimmy...

Like everyone, I regret the reduction of trophies drop but I understand it's necessary to keep the trophies sales rise as the company needs the money from it to keep the game running...

The money management of the game gets a lot more coherent now, but there is still a major incoherency :

The Blacksmith buys back Purple Items for only 3% of their sale price, that's just complete thieving and totally unrealistic...

In most other games, you can usually stuff for 50% or 75% of their retail value, which makes a lot more sense !

Fixing that problem could even boost trophies sales in the end, as people will be less reluctant to buy purple or blue items if they know they can sell them back at a decent price when they need to update them !
