Law school Blunders

OK, so applying to law school is difficult especially mixed with the fact that I am disabled. I sat for the February Lsat and scored 6 points higher than my first go (thank you Dave). I submitted my applications to my goal school and a safety school and I sat back and waited. My safety school emailed me and said they would wait for the February LSAT score; two days later I was rejected from them. I emailed them how I felt (politely of course) and reminded them of my LSAT and GPA. I also said I felt they were holding my disability against me. They immediately replied saying they didn'the know I had a February LSAT (mind you it was the same admissions officer from my emails) and put my application back into review.
A week ago I received an admittance letter from my first choice school, yayyyy! They called me and said I would receive my offer package in the mail in the next few days. A few days later I received an email with an attached offer of admissions packet. I was super excited because it said I was selected for a presidential scholarship and would receive full scholarship (I Thought I deserved it because I have worked for years to get into this school and even sat for the LSAT with gangrene). Then my hopes were deflated. I receive another email 12 hours later with a subject line "admission error". They said please disregard the last email as it was sent in error. I looked back at the email that said I received the presidential scholarship and found that was addressed to a woman in China!

Do these blunders happen often or is this my luck? I am happy that I was admitted but feel they toyed with my wallet.
