Exporting CHOPs seems to be pretty broken in Touch88. It doesn’t seem possible to remove or replace exports. I’m encountering situations where a field has something exported to it, but it doesn’t think it does, so I’m unable to remove the export.
Also, something which has been broken for quite a while since Touch77: replacing an export. A dialog box appears warning me that I already have an export to a field, but if I click “yes,” it invariably responds with an error telling me it’s unable to replace the export. I’d always work around this by first manually removing the old export in Touch77…
