So I was getting some weird behavior on my redactor fields. It wasn't consistent, but a lot of the time any text in-between double quotes would be wiped out and replaced with some a weird token, ex: [email protected]. The numbers were different most of the time. Again, it wasn't super consistent, sometimes it would work, others not so much.
But I wasn't getting any errors, something was replacing that text. I thought it was a bad paste from Word, but after playing with it enough to find a pattern, I finally got the attached error.
I don't have time right now to dig through and see where it's getting tripped up, so I swapped my YAML mode from quick to loose and it's working again.
Just thought I'd report it for the gentleman and anyone else banging their head on this issue.
