Steps:
I returned to the game yesterday and paid for 2 months, then i did the quest today to zone into circus tower, and joined the finder. got there and killed every boss, but on every drop it said that i couldnt loot anything because i loteed something allready. it is impossible, and i double checked every inch on my bags in case i loted something without any window.
But no, i had nothing and i didnt need on anything because this happened on the very first drop.
U can check the logs and see that i didnt loot anything there, what the heck, u can check that i didnt loot anything since 3 months ago and still says that i have loted something allready.

Eh, check your inventory maybe 1 fell to you and you did not notice, check also your armory..

like i said i checked everything many times and the time betwen first boss loot and the zone in was only soem minutes, so im totally sure that i didnt loot anything.
that is the reason im posting on bug forums, because im 100% sure this is a bug that thinks i looted this week when i didnt do it for sure.
im so sure that u can delete my char if u find that i looted something and im triying to get another loot for free.( to Square)
