A couple of questions:
* Was essentially the same board re-elected or is this an entirely new board? If new it could simply be stupidity (naivete). If the same board, I would be concerned.
* If this is a re-elected board, did they exhibit the same behavior before they were re-elected? If the same behavior, then sadly you knew what you were re-electing. If it is a radical change, I would be concerned.

The suggestion about contacting the managing agent is a good one. Keep in mind, though, that the managing agent company is hired by the Board and answers to the Board. They may defer to the Board when answering your questions.

Were the votes counted at the meeting or afterwards? Were any of the positions contested? Are there any big money projects going on or scheduled to start soon? If this is an experienced board whose way of doing things has suddenly changed, it bears looking into closely.
