The logic is that the player could be too busy micromanaging (adding stat points, 
changing skill shortcuts, just ordering the inventory, etc.) to read the message 
before it expires.

These big messages do not go to the "console", so once they expire, they can't be 
seen anymore. The player could potentially miss them, and don't notice they 
leveled up when a hacked bot defeat another bot because they were too busy 
managing their ammo and consumables.

Now, are these messages important? For example, if you drag an hostile bot into 
the town, and get busy trying to get invisible and survive, and the bot 
accidentally kills Spencer, there is a Game Over message. Would you actually miss 
it?

Definitely not a bug, though, so moving this to "idea". Needless to say, not for
