Pretty close! We used to have one string that was "CARDNAME can't block", and we would replace CARDNAME with, well, the name of the card. When the templating changed, we now had two strings "This creature can't block" and "This token can't block". And, on each card, we had to swap to the proper one.
For cards that had this string both for themselves and for a token, (like this one and Consuming Blob), the process that updated the reference for the token got overly aggressive, and replaced both the string talking about the card and the one talking about the token.
Thanks for the report, and we'll get this fixed up soon
