Tag Door goof

I've known this for a while but I wanted to point it out. Both doors circled open when one is purchased, it's the same door just two locations to open up the back top of the boat on Tag. However these doors are not the same price. The blue door in the left of the picture is 1250 points. The debris up the walkway on the right is 1000 points. As far as I am aware this is the only spot where you can do the same thing for a different amount of points. Tag is the only map where the cost of opening the whole map isn't always the same.
