Not that anyone cares or will likely notice but if a new model clashes with an old model who has not posed in 9 months or longer I will be disambiguating the two with cure id by adding it as a qualifier if it is available. This is the most reasonable method I can think of and helps circumvent this dumb (xiii) system we had going. It's not ideal but any solution that depends on looking up the model in the wiki every time we post isn't any better.

meru_(97148) and meru are the first real example of this.

This will affect very few models, I can only think of maybe 5 off the top of my head, but this should help prevent "Where did x go" questions.
