Race condition

[deep-42-thought]

We had an error that looked like being caused by a race condition:

• The vote of one participant A was displayed as "3" for two participants and as "5" for the other four participants (including participant A).
• The participant A said, he clicked "3" first, but then changed his mind towards "5" and clicked "5" instead.
• The change might have happened, right when the team leader (not participant A) revealed the votes.
