ManiaPlanet crashes in Editor

[ThaumicTom]

The game crashes in the Editor. It happened to me in the Valley Day Editor. I placed all four Cars that can be found in the Items folder and then tried to drive the map and placed my car right above the Lagoon one.

Painful start, I guess.

Edit 1st Feb. 2019: I can't reproduce it anymore myself, it's probably fixed, thanks Nadeo!
