i lost my chemist

[Nah, I’d win]

I lost my chemist when I was in the farm made a setup from youtube I put all the devices then I hired employees and said that they will do but not yet paid then ordered a bunch of goods with delivery and when the car arrived with delivery one chemist was stuck when the other he went out of the fence a little bit with a slope and when I have already put money in the corvati employees I see that one is missing everything works but there is no one of my two chemists. What can I do?
