This was so fun to make!! Hope y'all enjoy, this is a comment for any errors or things like that if you need help working through it :)
You can just put an empty pie pan in the oven and it doesn't come out again, thus locking yourself out of one of the ovens.
Just played to double-check, but you should be able to grab anything out of the oven manually. It only shoots out completed pies :)
