I experienced the following issue:
- After installing the latest build, I created a Content Part called "Sport", adding a single "Name" field as an Input Field. Saved it.
- I created a Content Type called "Sport", adding a "Body Part". I looked to add my "Sport" part to it (with the intention of having the type separate from the part, but it was not listed.
- I clicked on the "Content Parts" tab to look for the "Sport" part and did not find it. I tried to create it again, but I got an error that it already existed.
- I clicked back on the Content Types tab and selected my Sport content type. I still could not find the "Sport" part to add, so I decided to add a "Name" field. When I did so, the "Technical Name" of the field appeared as "Name-1",
which should be a mistake, as I have no conflicting "Name" field on the type--only the "Sport" part that I now cannot find.
Of course, I now have no way to delete the "Sport" part to get back to a good state.
This is probably a pretty serious error. Let me know if you have questions, and I will look into it myself.
