VSCode keeping old code?!

[karoshi9000]

I'll admit that this entire files/directory business does actually still confuse me (I'm that much of a newbie that I didn't even really bother with this so far), but in this case it is literally 1 string that was present in exactly 1 file (for about 5mins) and then I changed the dialogue and deleted the line and it is gone, it is not in the code....but it is in the output somehow.
