[New] Gate Returned???

Hi, my initial gate (LHR) has been automatically returned on the first day of the second month. I thought my unused gates should not have been returned until the end of the second months. (I mean at the first day of the third months, unused gate will be returned)
So I see somebody else still have 5 gates, so I'm guessing those are their initial gates. my gates are already on the negotiate session, so maybe somebody else might be able to take them.
However, if it is a bug, I would like to get it back to me again, and if it's not a bug, I just want to make sure about that.


Thank you very much
