Nested blocks not showing in panel after conversion from nested builder field

Hello,

I recently converted a template and blueprint from the old builder plugin to blocks. In the old blueprint there was a builder field that had one field inside that also was a builder field. I changed both to type: blocks and in the template I changed from $field->blocks() to $field->toBlocks(). The data from my pages that were created using the old template is showing on the frontend, but in the backend the nested blocks fields say “No blocks yet”.

What can I do to enable editing the field data again?

nothing? this is affecting a commercial site. i’d love to help debug this, but right now i don’t know how.

Maybe try posting your blueprint and txt content here, otherwise the issue becomes really elaborate to reproduce and debug, making it hard for people to help you.
