There has been an issue where matches are locked for their entirety. A few other dota bettors and I have mentioned it before and a mod has escalated it. When that happened the sports team confirmed it was unintended and would be fixed. To their credit, they have fixed it for the most part.
For some reason, this issue only occurs now for the China DPC matches and it happens -every- single match. The line goes up, map 1 is locked for its entirety. The second map 1 ends, map 2 is locked for its entirety, and so on for map 3. Just wanted to point this out.
