Brawl mode scams for items if u try to change upgradeable item

[nicaea_sera]

I tried to get my hardly earned legendary by selling 3200 cooldown item, what i got in result is 1600 cooldown, ui stuck in item selection with no items to choose, and no legendary

Feel like this could have happened caz i bought 1600 cooldown item that i then upgraded to 3200 in other round
