Service Connect - Create Sub-workflow schema

Hello, In my workflow there is a part where I’ve built a Sub-Workflow that needs to cycle. After setting up the cycle and clicking the “Create sub-workflow schema” button, I give this new schema a name, and click OK. My input file is in XML.

After I click OK, the screen just hangs. It sits there and processes continuously. I got curious and tried this in a totally separate environment and it did the same thing. I let one of the screens process for 4 hours straight… still processing.

So either my XML is messed up somehow, or SC is? Anyone encounter this before?
