Greeting,

So, I've been encountering some type of bug, at which whenever I try to trade with a specific person through clicking their username, and select "trade" the trade doesn't send, and it happens the same to them towards me, not sending either. Only when we select "trade" through the friend's list does it actually work. It began happening after I changed my username, due to having a free name change (User ID #0000), then after that, such bug occurred and is still doing so, even though it has been around two weeks already. It doesn't happen with anyone else that we either try to trade with through the usual means. We've deleted each other from our friend's list to try to see whether that fixed the problem, however it didn't.
Therefore, I wanted to report it here to see if anyone has either had the issue before and/or knows of a solution, as it can get quite bothersome to not be able to trade properly.

Additional info: I play on the website Deadmaze.com and the other person plays through Steam.
