I did a recent mass rename batch but now in Dynamic Category view they are all missing previews (that were viewable pre-rename). I have purged the heck out of it and its been over a day since the mass rename batch. Does it really take wiki that long to adjust the cache or do you think this is a bug and I should special contact it?
