should i make a new save for this or can i keep using my old one?
To avoid bugs, you should create a new one. If you don't want to start all over again, you can use the mailbox located outside the front door. it allows you to transfer props between saves
truth be told, i didnt even know thats what the mailbox was for
If you have a KerfurO you can blow it up or have it ride the atv while you crash it and then put the parts in your mailbox!
