i was wondering if there is any way to adjust the tracking of the cursor when harvesting,planting or plowing?
when i do those things the cursor is all over the place and i do crops that i dont want done and i need to delete and start over.
also one other question
is it possible to get hacked? i have been recieving messages about hackers and have seen them in different rooms.
is there anything to be worried about?
thank you.
