NEW UPDATE 7/14: It’s back! This time without busted your beloved hotkey. The two new commands should now work as intended with no ill side effects.
Roblox has two new commands accessible via the right-mouse context menu:
Paste At Original Location and Paste Into At Original Location
Each of these pastes the selection at the location it occupied when it was copied, as opposed to other objects in the scene. This makes it easy to copy objects directly from one instance of Roblox Studio to another without needing to resort to complex workflows.
All the paste variations have the same behavior, whether collisions are enabled in the ribbon or not.
The two new commands do not have default hotkeys, but you can add them using:
File → Advanced → Customize Shortcuts.
