[OPEN] Ambulance stucked

Hello,
One of my patient has been transfered to another hospital and his ambulance has been stucked on the road for some days.
I'm adding a screenshot as well as my save.

Ok, so I just realized that I have been able to purchase the ambulance (not intentionally) before unlocking them.
That's probably why I wasn't able to move it, and that's why I thought it was belonging to another hospital.

Hi, thanks a lot for the report and the update, that latter could actually help us reproduce it - luckily it seems that at least the ambulance isn't blocking anything in the save, although it's a very strange situation, the dark gray color usually marks the 'external' ambulance that takes patients away.
I have a hunch that this could have happened as a side effect of other issues we introduced/fixed last week, let's see if we can easily prevent this from happening in the future.
