I have to reset the field permissions every time I edit a field. Resets to default (no access) after every save.
You wouldn't happen to be using the contrib module Login Toboggan, do you? I'm investigation a problem that sounds like yours and I've tracked it down to Login Toboggan.
Yes I am using it.
Then your problem is likely the one described in this issue: #1365764: Adding logintoboggan.permissions.js causes error if Drupal.settings.LoginToboggan not set.
Just for reference, it sounds like there's another conflict with LoginToboggan too: #1407564: CSS conflict with logintoboggan, prevents using Custom Permissions (field_permissions module)
But if I understand this issue correctly they are actually not the same bug...
I am having the same issues on our site. However, I'm not using LoginToboggan. Do you have any other suggestions on what this could be?
