Thanks for the issue reporting!
Fortunately this is not really a problem just a warning (which sadly get outputted to the log as if it was a real problem).

This issue is discussed here: https://github.com/neitsa/PrepareLanding/issues/45

Technically, the keycodes strings that come directly from unity are not recognized by Rimworld. I tried some stuff to no avail, yet, to fix this bug. I'm still certain it's not something really hard to fix, but haven't found a correct way yet... I'm still digging :|
