yeah when you fail (or complete) a level, all the points get stuck in whatever icon they were last on, that's normal, but I'm worried about that "every car explodes as soon as the level starts" issue.
if you don't mind me asking, did that happen after you tried moving any point? (could also explain the point stuck in moving state)
or did that happen literally the moment the level loaded?
And did this happen every time you restarted or just once?
sorry, just trying to look into this
