Void fissure Relic selection screen got stuck for a while

[M0RGION]

On a Void fissure Defense mission in the Void, after wave 10 or 15, one of the players got shown still selecting a relic even though the selection timer had run out. It got stuck like this for several minutes with no timer visible and accepted no input apart from the chat interface. As you can see from our chat, we assumed he had disconnected. We were about to Alt+F4 but the game (fortunately) continued. The player hadn't disconnected and played the rest of the match normally. He never communicated with the rest of us so we don't know what happened meanwhile on his client. As you can see from the chat, I used the /unstuck command to send an automatic report when this happened.
