Error opening older-version files

[tomalisch]

I have been encountering a weird error with the newest MARGO version when trying to read in .raw files. Specifically, the error occurs when trying to assign an already attached .raw(). There is an orange notice referring to a path mismatch/repair when loading in the expmt.mat. When manually attaching the object, the raw mat shape does change to reflect the underlying structure (i.e., frames on one axis) but it still errors out when trying to assign/access the .raw().
