I'm getting more and more insulted by people assuming that I can't look up what type of SVN update actually happened.
And, obviously, manually deleting the "deleted" files when I copy-paste-overwrite Assets (the most common source of "updated" files).
I think I even said this explicitly in the past.
Not to mention that this time I actually killed Assets entirely and replaced it afresh from SVN.
So, NO, the cause is NOT related to "unnecessary superfluous files".
Not to mention how the error message is quite explicitly complaining about Afflictions being absent.
I'll wait for the fix, but this was NOT my fault of "being clumsy with files".
That said, in SOME cases you actually do need to first remove the files you are copying, because they react badly to overwriting attemtps.
But this is unrelated to Civ and is a totally separate problem of "file ownership" or similarly.
And it would still be avoided by killing the entire folder and copying it anew, anyways.
Whatever.
