Answer options for question no longer show in the designer. See example of screen shot below. It seems to affect all questions with User defined Answer Options in the questionnaire, and across other questionnaires. We have not edited the questions nor answer options. My colleagues just confirmed that they see the same on their laptops. This issue must have been introduced in the last few hours (maybe few days).
When compiling, no error (< 2 answer options) is shown, so I assume they are still connected. However, if saving a change to the question, the answer options are removed.
