3 frame corners square, but 4th not.

I'm reassembling my frame to make sure it's 100% square, and I have run into this problem. in Frame assembly step 12, I'm checking the frame for squareness, and 3 of the 4 corners are square. am I incorrect in assuming that the only way it can be true is if my square measure tool is bent (i checked that a coulpe of times), or one or more of the 3030 extrusions are not the same length or one is slightly bent?

found my issue. the 3030 extrusions are a tiiiiny bit bent. I'm pretty sure it has happened during transit. We had problems when I received my items a lot of things were missing, and some things were in a new box. So it's definitely not the fault of the nice people at RatRig. (also it's a long time ago, so it's very much my own fault for not checking it when we found out my boxes were dropped during transit)
