I read all that then and now but it doesn't seem to address the issue.
So my question is: If the bank is negative what happens to the footprint of that vacation period. When I was awarded a line that had a trip that fell into that footprint, even though I had a negative balance, the trip disappeared from my calendar. I was able to slide it away from the vacation period, so I got it back, but I wonder what would have happened if I couldn't have slid it and why did it go away in the first place?
