RPG Maker MV - How does "Erase Event" work? Why it doesn't work as you may want it?

Hello, y'all, your clumsy RPG Maker MV veteran, +5k on the platform here to deliver a little tip. Also rarely streaming RPG Maker MV. I love sharing wisdom and help tidbits to beginners and more experienced players, if my knowledge can help :3

People may forget that there exists a thing called "map refreshing", which happens each time the player reenters a map. What this does is start the map with every event that there is, even with those that you have set to be "erased". It's just that, when the map refreshes, the events need to happen again in order to end up being "erased" :) This also happens when you teleport the player on the same map. Or should happen as far as I know.
