ManhattanTowerLadder.script - Game Crash when deinstalling while Person in Basket

[Aleks1234]

Good Morning, Day or Evening dear Community,
The title mainly explains the issue that I can get to solve.

When deinstalling the midmount ladder and a person is inside, the basket. The game crashes shortly after.
Now, my plan is it to add an "else if" or and "if" that blocks the deinstalling  function when a person is in the basket.
As well as I want the function toe be blocked when a hose is connected to the vehicle

My Skills are sadly not evolved enough, so now I am asking for assistance to make the plan reality. 

I would be very grateful if a person from this community could assist me with my issue.

Best regards Aleks
