Mysterious Record Type change on Details Page and all the Page Variations in my Community...

Hi! I'm building a Community...One minute I'm working on my Case Details page and the 3 Page Variations, and everything is great. The next minute the Case Details page and the 3 Page Variations have all been replaced 90% (there were still a couple rich text boxes that remained from my pages) by the pages of another record type from another project that's not part of my community. No one can figure out what happened and I don't want to start over. Anyone experience this?
