Last week I tried to change an answer during a live quiz. I realized the mistake just in time. The correct answer was set to 240-260. The correct answer was 250, wanted to give players a margin of 10. But the correct answer was 251, so ik had to enter 241-261. When I did this, the answer was set to 0. In no possible way I was able to set the correct answer. Therefore I lost the question during the live quiz. Bit of a bummer and public blooper

.
I haven't tested it on other answertypes, but perhaps it related to the other answers-types too.
