Have you ever done something on computer but forgot to save or it somehow not saved?

Back when I used to make videos a lot for my YouTube channel, the program that I usually use doesn't always autosave. It usually does but it's not always perfect. So sometimes I would lose hours of work, especially if something happened where the computer turned off abruptly. Sometimes even when my computer would do automatic updates (you know the updates where it turns off your PC and you can schedule a time, mostly when you're sleeping or are going to be out?)

I know this isn't a huge deal because it didn't always do this and it's definitely not my actual job but still. It was pretty annoying.

not personally since I tend to save regularly especially if it's an office type document like word or excel or something

Not exactly forgot to save. I did some college work, saved all the recent versions on my home computer and put them into USB to take to college to upload them the next day. I made double and triple sure I 100% saved very new version, there must be been around 20 pages of new content.

At college I realised I left my USB still in my computer at home...

yup, it has happened to me some times at work. i've had to start whole reports and analysis from scratch. it's incredibly frustrating, but i've come to a point that when it happens, instead of being angry i just concentrate my energy into restarting it

but it really really sucks

Yes it has happened but now I'm smarter and remember to save my work. It was one of the first rules I learnt in computing.

Yes, and I hate it so much. It’s so frustrating!

yes and I proceeded to cry alot afterward

Luckily it has not happened to me, because I'm so paranoid that I keep continuously saving my work and making back-ups. This saved my ass in many situations.
