We lost a game because blue team and red team inhibitor message overlapped each other and got no mes

We didn't get the message that shows the inhibitor was going to spawn. Kled and Sion ulted to destroy the nexus just to realized it they weren't able to. We lost that game I can't believe that nobody in the Functionality team never tried to test that. What would happen if the announcer has to announce that both inhibitor would spawn. There should be a message displayed but yet none.
