It's working now! Thank you. Sorry for all the problems with this thing.

Now that it's working I'm trying to figure out the include/exclude metadata thing.

I managed to get it to remove other tagcategories if it detects crossovers and that's working but now I'm stuck on this.

Here's the replace_metadatas used (I took out all the non-relevant ones):

replace_metadata: 
 site=>www.fanfiction.net=>FanFiction.net
 site=>archiveofourown.org=>Archive of Our Own
 category=>(\(Video Game\)|\([0-9]+\))=>
 tagscategory=>^(?!.*(Half-Life|Portal|Mass Effect|Crossover)).*$=>Other
 tagscategory=>^(.*)$=>Fanfiction.\1
 tagscategory=>(Portal|Half-Life)=>Half-Life & Portal

include_metadata_post:
 tagscategory==Crossover&&category==Crossover

exclude_metadata_post:
 category==Crossover&&category_LIST==Half-Life, Portal

I have this fic, and I'm trying to get it to result in:
Categories: Half-Life, Portal
Tags: Fanfiction.Half-Life & Portal

But instead it results in this:
Categories: Crossover, Half-Life, Portal
Tags: none

Furthermore, this also resulted in no tag whatsoever on other crossover fics that has either Half-Life or Portal in its category, e.g. this one. Crossovers that contain neither of them still work as expected.

Changing either/both of the _post to _pre results in the Fanfiction.Crossover tag appearing in both test fics.

Changing the exclude (post) to tagscategory results in missing tags on both fics.

I noticed in the crossover thing it said this:
## Applied *after* category replace_metadata/include/exclude_metadata

So I wonder if that might be why it doesn't work.

Any suggestions?

EDIT: As well, I just noticed that a fanfic from AO3 categorized as both "Mass Effect - All Media Types" and "Mass Effect Trilogy" got the Crossover category, even though I have a replace_metadata to transform it into a singular category.

 category=>(^(?=.*Mass.Effect)(?!.*Mass Effect Trilogy).*|Mass Effect - All Media Types)=>Mass Effect Trilogy

(yes it's pretty kludgey-looking but it keeps me from getting "Mass Effect Trilogy Trilogy" as a category)

Confusing because the comment about replace_metadata indicates that this shouldn't happen.
