Yes, mistakes do happen, even with a computer.
I was Vice President of Recruitment in 2001 and I checked the list each day to see if the women we invited back declined or accepted bit since things are so hectic I could only do it after parties were over. We only have 3 rounds here, too. So after 2nd rounds I saw that three PNMS we had invited back were neither listed as declined or accepted. I called panhellenic and was told that WE had dropped THEM... I knew this was wrong so our membership chair and myself went to the office looked at our cards and then panhellenic had to admit that the computer had screwed up and those three girls were accdentally dropped. We had to get our chapter together and decide what to do. In the end we invited the three girls back to prefs and had hte rho chis explain what happened to them. Two accepted and one of them is a sister.
But, yes, it does happen. That is why your chapter's membership team needs to review all of their lists EVERY DAY!
