Our user that got this error says he was in the act of inserting a new question to an existing assessment (Using the drop down choose question type drop down) when this happened.

I just got a bug report for this in IDEAL, but I can't seem to reproduce it myself either.
We're on 2.2.x from a few weeks ago with some modifications to Samigo.

Tried many different test cases (single part, multiple part, randow draw, different type of questions) but cannot reproduce the above error.
Bug report from T&Q. User behaviour is unknown. 2-2-x, r14286
