Iphoto deletes events when adding events from flagged photos

Question

Dear community,
Whenever I use flagged photos, previous events get deleted. I don't know whether this is because the photos can only be in one event at a time, or that this is erroneous behaviour.
In my logic, there should be possibility for as much events as you deem possible, yet it is mind boggling, that you don't have an automatic option, that makes you put photos in two events. Also it is mind numbing that you can't just copy & paste the pictures anywhere you like. You can paste in albums, but not into events.
You have an option to "Create event from flagged photos", yet not an option to add photos to an existing event, you must flag them first.
Then there is the sudden discomfort of brain pain, when you find out the previous events you've created stopped seizing to exist, and you have to sift through 500 photos, just to find 3 photos you've flagged in the creation of a previous event. Which defeats the purpose of creating them.
The albums work good for this purpose, yet I want to be able to pin albums to the back board, where the events are. Or have events that will not disappear, may contain doubles with other events, or/and aren't restricted to copying into them. It would save a lot of time, to just CMD + C, CMD + V.

You're confusing Events and Albums.

A photo in two Events is using twice the disk space. An album just references the photo in the Library and can be in as many albums as you like while wasting no disk space.

Eh, you have to flag photos first before you can create an Event from them too...

Flagging photos does not delete Events. Emptying an Event deletes them.
You can't have what you want.
