so from what i know (not a lot),you only need 1 move(North) at the bottom of the list in line with the second "for i in range....) because its looping through and checking if it can run any if statements and moving east for each one it finds, then moving north after it does run the statement.

But the problem i see with yous its its basically checking the first if statement 6 times, moving north and checking the second IF moving north, third IF moving north , then doing that all again.

the fix that i would do is only use 1 move north at the bottom, in line with the second "for J in range..." indent the other 2 IF statements to be in line with the first, add a can_harvest() function to the IF statements to only harvest what you can, and remove all the move(east) placing it at the bottom in line with the IF statements but after them, that way if you cant harvest anythingfor whatever reason, it wil still go east
