UCSD ECE发错拒信了……

申请的UCSD ECE的电路方向。上周五晚收到拒信万念俱灰，本来觉得有把握的学校，导致我对后面的学校全部丧失信心。。结果周日晚十二点收到另一封邮件。内容大致如下：
We understand that you were recently sent a letter of rejection from UCSD's Graduate Division. This was sent to you in error. Indeed, the Electrical and Computer Engineering Department wishes to nominate you for admission you to our Master's Program. This error will be fixed as soon as possible; you will be sent an admission nomination letter shortly.
意思貌似是发错拒信了。是要录取我吗？这种小概率事件发生在我身上觉得有点不敢相信。再发邮件询问回复如下：
We are working with the Graduate Division to reverse the rejection. Thank you for your patience while this is resolved.
求鉴定。是ad吗？但是一天过去了也没收到啥信呀。
