AA is bugged, I think you are only able to trade/deposit around 50,000 every time. Try smaller/larger amounts and see for yourself (try 1 AA to make sure it works, then try 10, 100, 1000, 10000 etc. and see where it stops). It’s the same when you try to trade AA with someone else (if you try to trade a lot it won’t get added). I am not sure why this is happening but I will take a look.

Thanks @aodstorm
