I sure hope you're right about the computer making an error. it sounds a little fishy to me that it would start eliminating my stays each time i went to the site. I viewed my account twice in 2 days and each time a stay was deleted. I'll see what others say before calling them. I suggest everyone to start tracking on an excel sheet. Everytime i see the points registered, i highlight it in my sheet. This way I'll know when they decide to mistakenly vanish my pts.
Hold tight!
