So, this happened to a teammate last night, and I thought he just messed up. But he swore he didn’t.
TL;DR: Last Update to Epic Launcher is BROKEN, do NOT delete any projects from it. Issue: Deleting projects from within the Epic Launcher (not sure if it’s random or every project…because I’m not going to freaking try it again) causes other ones to be deleted as well. They seem to be linked somehow. They were right next to each other when I right-clicked deleted the one of the left…taking out the one on the right as well. Sadly, I was not thinking and just hit Yes after the warning CLEARLY showed me that I was deleting the right one… So yes, I am at fault for just clicking through but my brain wasn’t as fast as my fingers were.
There is definitely an issue though if you attempt to delete one project and you end up deleting not only that one but the one next to it. Luckily for me it was just some random projects. But for my teammate, he had to redownload the depot…
Also, just noticed you can’t delete more than one at a time, so this makes it even less likely the error was user-related.
