[2.0.73] Blueprint editor forcefully discards changes when dropping the player to a planet

[sben]

When a player is dropped from a space platform (after reaching the destination planet),
the blueprint editor is closed and all changes are discarded without warning.

I don't know if this counts as intended behaviour or not, but it feels wrong and I would see it as an edge-case UX bug.

there was already a similar (already fixed) issue: 130162 Opening map while in blueprint editor drops changes without warning
