I know this is more so the fault of the player but I suggest for a confirmation window to pop up if you hit “Enter” for any instance. That, or for an entrance count not to be used up if one hits “Enter” accidentally, and as a solo player.
Personally, I want to hit “Search for a Party” often. However, when the option pops up, your mouse is immediately placed on top of the “Enter” button and mistakes can be easily made.
