Do not save and put it back.
You have to put the fix before losing the car because it doesn't make it come back.
I'm going to look to put a fix that can bring the car back but it will only work if you have the car.
For example: I can add an extra option when the car is in front of the hero's house which will bewitch it using 10 droplets (it's not much) and which will make the car move alone when you sleep. The car will park in front of the house where you spent the night and the fix will activate when the spell is activated.
This is the best solution so that even old players can get the fix and at the same time I fix the problem "I forgot where I left the car"
that was reported to me.
