overflow config file is not in the right place

When running the pr suite, I noticed a planar directory that I wasn't expecting. It turns out that the overflow config file is in planar rather than ocean/planar. We should fix this at some point.

This one's on me. Thanks for catching it

Not a bit deal at all, just figured it was better to point it out when I noticed it.
