OAuth v1 missing data for user

We have a Patreon login on our site that people use to access WIP builds. This has worked fine, until now. A single user is experiencing problems. As it turns out, Patreon API will not return any pledge information for this user, even though they’re pledged! The entire “included” object is missing from the API response.

I sent patreon an email, and they referred me to this forum.

To protect user privacy, I won’t share their information openly in the thread, but I would be happy to provide more information in PM to Patreon devs.
