Late application horror stories?

Has anyone else ever applied late to a desired or back up school and missed the deadline for whatever reason?

To share I tried applying to a backup school as a transfer student around 11PM before the 12AM deadline. Everything took so long to upload that by the time I tried to submit my application it was too late.

I also slept through another application deadline but at least I got into my desired school.

When D applied (3 yrs ago) she changed her mind to EDII at the last minute on the deadline and the upload failed and missed half her application at print preview! She emailed her admin officer who hand corrected everything and got it all worked out but STRESSFUL 24hrs!!! S has everything in 1 week to 2 days early (12/1 deadlines - music major). MORAL - do it early. btw…D accepted and happy at EDII school.
