Hi and thanks for the feedback. I should explain that the streams are fully automated and nobody is actually controlling the games (since they're running 24/7 for several months). There is just a couple of scripts that start and stop the matches according to schedule. And the communication capabilities of scripts is limited :)
The problem you described is quite rare - you see, the games run on two separate virtual machines and they are sometimes restarted when the timing on machines is desynchronized. Then it sometimes takes some time and a few restarts for the machines to sync. Even though this doesn't happen often, we're planning to reduce this issue next year.
