This is a such an odd one:

```plaintext
PrettyText.format_for_email(p.cooked, p)
=> "<p>Hello, I’m currently trying to follow a machine learning pipeline described by a paper. Essentially, I need to create an input matrix which is shaped N x KSDT sized. The paper describes this as: “Here k, ks, kd, and ksd are labels and not indices, and all terms are understood to be matrices of the same N x KSQT size, so e.g. Xk is not an N x K sized matrix, but the full-size N x KSQT matrix with N x k unique values replicated KSQ times”.</p>\n<p>Right now, I have three following np.arrays:<br>\nbias_block: (348, 2, 151), bias_contrast: (348, 5, 151), and bias_decision: (348, 2, 151).<br>\nMy understanding is that in order to combine these three arrays, I would need a final size of (348, 20, 20, 20, 151). However, I’m really struggling on how to combine these arrays. Could someone please help with this, thanks a lot.</p>"

```

I am not seeing what is wrong with that string … the N x KSDT does not appear to have anything hiding there.

(note the post has now popped out of latest, so rss is back and working as a side effect, but I certainly would like to fix this.

I am assuming this is the line where this originates from:
