This is just to bring attention to a matter not so important or serious, so don't take it too seriously.
There should be a seperation between EVENTS and INVASIONS. Invasions last for as long as you haven't killed enough enemies. Events last for a night (except eclipse, which last for a day). These are not official terms
And since you can only summon frost legion, pirates and the Frost and Pumpkin moons, whereas Eclipse, blood moon and goblin invasion happen by change, they could be divided to SUMMONED and NATURAL
These should be taken to notice when editing pages.
