|Description:||I was attempting to fix some tags on a vandalized image (#669333), at least trying to revert back to the version with the most complete tag set (2009-12-24 03:12:55) before making further changes, but it just resulted in "tagme" as the sole tag after the revert.|
I tried this again on #669294 (not b/c of vandalism, just to test) and tried to revert to the earliest possible version. However, this time, nothing happened at all.
So, in the end, I'm not quite sure what's wrong with it, but I assume that something is.
And, on a related note, the Notes history does not work at all (which I'm sure you're already aware of).
