Here is what they should have said in 9/17 Development update

Gosh you guys are just triggering me tonight. On that subject, I’m curious if the game checks package integrity on launch, and if it does, to what extent (hopefully not just checking a version number). I purchased through steam, and steam has its own integrity checker, but it doesn’t work for games packaged like MSFS2020. Maybe I’ll go over to the wishlist later and add a manual integrity checker (that validates checksums)… Thanks moxie!
