They are unfortunate, but part of the game, I seem to regularly lose a plot of land when I am in 2nd place. And the last time I lost a plot in second place I was already 1 plot behind everyone and just purchased the one I lost at auction for over $1000. This was in about round 6 so at this point I lost game, the other players overtook me by leaps and bounds after that, they were able to afford more plots and by the end of the game I was down about 4 plots from them and lost by a very large margin... I never complained tho, really I didn't ;-)
2nd place should lose a land relatively rarely compared to the player in 1st place. I agree with the original game designers that 2nd place should lose a plot 20% of the time, and 1st place should get the event 80% of the time.
