If you have a repeater that is already being used, in a template, and containing content, ie
$repeater
|_ body (this can be any field)
|_ image (this can be any field)
And you add a filed to said repeater,
$repeater
|_ body (this can be any field)
|_ image (this can be any field)
|_ summary (this can be any field) When you want to update existing instances of that repeater item the it does not want to save that repeater field, I cant delete upload or add new items to this repeater.
Is this a bug?
Do you need more info?
Should I make an issue?
