When client joins game and host has yet to load in, client can skip debriefing and deploy. Game will then start on clients end. If client opens a menu by pressing "Esc", The UI Hud overlay will stick on screen if it is still up when host joins. Client can then open a second menu by pressing "Esc", but not close the first. Client and host was on different regions when bug was discovered. Not clear if latency had any affect.
Steps to reproduce: Open a new multiplayer game as host. Have a client join game, ready up, skip debriefing and deploy. Have client open menu by pressing "Esc".
Thereafter continue to deploy as host.
