Building models for colonies you haven't finished placing still appear after reverting flight.

[MutatedRaincoat]

If you click "Build colony," then place buildings but revert flight at some point, maybe because one of the models had an invisible collision box that destroys your vessel, then go to the same spot to place your colony, the models will still be there afterward. They'll even appear in new saves.

To Reproduce

1. Launch a vessel with enough RocketParts
2. Use the Set Position cheat to place the vessel on a body at a set of coordinates (e.g. Minmus Lat. 0 Long. 0)
3. Right click the command pod and click the "build colony" button
4. Revert flight to vehicle assembly
5. (Optional) Create a new save file
6. Launch another vessel and use Set Position to place it at the same coordinates as before
7. The colony building models will be there when they shouldn't.
