Connect a lever and a door

Use a WSRF Stable ID instead of storing the lever’s UObject reference as persistent world state.

Steps

1. Add WSRF to both Actors and assign the same Region.
2. Give each the behavior appropriate to the puzzle. Use Custom/Advanced setup if the standard presets do not match.
3. On the door, implement WSRF Resettable and store bOpen plus the lever’s Stable ID in Custom State.
4. In WSRF Prepare For Reset, stop both animations and reject new interaction.
5. In WSRF Restore Custom State, restore bOpen, call Find Loaded Actor with the saved ID, and handle a null result.
6. In WSRF Reset Completed, update visuals only after all state required by this Actor is available.
