On new rounds after Round 1, “YOU PLACED 1” becomes locked on the screen, general UI does not populate, and Cursor stays active after scoreboard is displayed. Issue makes Island unplayable after Round 1.
You cannot see the Windows cursor in the screenshots but it remains active on the screen. To look around you have to click and drag as moving the mouse will move the cursor.
Tested with 2P - Issue occurs for the losing player and persists indefinitely across rounds. If a player has not lost, the issue will not be present to them. Once a player has lost, the issue will continue to be present.
