Minecraft: Do uncharged Minecraft worlds need (with multiverse core) RAM?

- in Worlds

My question:

If I unload a world with a multiverse core via / mv unload [WORLD], does it still need RAM?

gl

Yes

It is then only unloaded, but still there

As

No, you don't need them because nothing can change in them and everything has already been written to a storage medium
