It would probably help to have a full log of exactly what has been checked and what hasn't. Also, as a general rule, it would be best to start with C supports and work forward, instead of working backwards from S supports, since preceding events will inform the context of later events.
In any case, some things that don't appear to have been addressed, from the top of my head:
- Basically all Goldmary supports need to be checked, as the localisation team really hated how she talks about femininity and attractiveness and so on. Rewrites for her were very common, both across bonds and supports. Her bonds with Leif are one example, and her supports with Yunaka are another.
- Similarly, Panette and Timerra have many conversations relating to femininity which were rewritten. One Timerra support with Framme has their discussion about clothing changed, for example.
- Fogado had lines relating to hitting on Alear written out of his supports.
- I kept a notebook of text to reference myself later regarding changes, which I haven't gotten around to doing yet. I can't remember what these were relating to, but here are some of the examples I noted to myself as warranting checks, which haven't been covered yet: Alear x Ivy B support, Clanne's wakeup lines.
- Also, there's the matter of several characters arbitrarily having their names changed in the localisation. Mystira -> Timerra, for example. If the patch wants to serve as a proper retranslation as the end goal, I think reverting these changes would also be worth doing.
Honestly I think the most sensible course of action is to do a full TLC on every support on the game, as time consuming as it would be. There's simply too much that Treehouse fucked with to assume that anything wasn't touched.
