Planting fix and quality of life improvements

Hey everyone ! Thanks for the feedback ! I fixed some minor bugs:

• Seed model stuck above head, but could still pick up new ones
• On the first new field the plants appear in space
• On the second new field one of the fields wasn't clickable

Also I tried to make the path-finding smoother so you don't get stuck + if you click on a machine you now move to the machine !
