You are right, Kmessinger.
I just copied the permalink I’m using. It’s too complicated for an example. I’m sorry.
This problem will be fixed in version 2.7.1.

In RSS (XML) files, ampersand marks should be escaped, but not escaped.
This is probably due to WordPress’s problem. You have done nothing wrong, Rocketllama.
If you use default permalinks, such as /mydomain.com/?p=XX, it occurs.
If you customize your permalinks, for example, /mydomain.com/%year%/%month%/%post_id%/, you will get a legitimate RSS.
Please try cutomize permalinks. [Admin Panel]->[Settings]->[Peramlinks]
